Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122664, here are decompositions:
- 11 + 122653 = 122664
- 13 + 122651 = 122664
- 53 + 122611 = 122664
- 67 + 122597 = 122664
- 103 + 122561 = 122664
- 107 + 122557 = 122664
- 131 + 122533 = 122664
- 137 + 122527 = 122664
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 122,664 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 122664 first appears in π at position 419,135 of the decimal expansion (the 419,135ordinal-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.
