Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122646, here are decompositions:
- 37 + 122609 = 122646
- 47 + 122599 = 122646
- 67 + 122579 = 122646
- 89 + 122557 = 122646
- 113 + 122533 = 122646
- 137 + 122509 = 122646
- 149 + 122497 = 122646
- 157 + 122489 = 122646
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 122,646 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 122646 first appears in π at position 864,507 of the decimal expansion (the 864,507ordinal-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.
