Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122746, here are decompositions:
- 3 + 122743 = 122746
- 5 + 122741 = 122746
- 53 + 122693 = 122746
- 83 + 122663 = 122746
- 137 + 122609 = 122746
- 149 + 122597 = 122746
- 167 + 122579 = 122746
- 257 + 122489 = 122746
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 122,746 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 122746 first appears in π at position 280,911 of the decimal expansion (the 280,911ordinal-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.
