Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122708, here are decompositions:
- 7 + 122701 = 122708
- 97 + 122611 = 122708
- 109 + 122599 = 122708
- 151 + 122557 = 122708
- 181 + 122527 = 122708
- 199 + 122509 = 122708
- 211 + 122497 = 122708
- 307 + 122401 = 122708
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 122,708 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 122708 first appears in π at position 220,119 of the decimal expansion (the 220,119ordinal-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.
