Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120878, here are decompositions:
- 7 + 120871 = 120878
- 31 + 120847 = 120878
- 61 + 120817 = 120878
- 67 + 120811 = 120878
- 139 + 120739 = 120878
- 157 + 120721 = 120878
- 271 + 120607 = 120878
- 367 + 120511 = 120878
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 120,878 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 120878 first appears in π at position 434,296 of the decimal expansion (the 434,296ordinal-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.
