Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123722, here are decompositions:
- 3 + 123719 = 123722
- 61 + 123661 = 123722
- 103 + 123619 = 123722
- 139 + 123583 = 123722
- 223 + 123499 = 123722
- 229 + 123493 = 123722
- 283 + 123439 = 123722
- 349 + 123373 = 123722
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 123,722 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 123722 first appears in π at position 234,780 of the decimal expansion (the 234,780ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
