Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146780, here are decompositions:
- 3 + 146777 = 146780
- 13 + 146767 = 146780
- 31 + 146749 = 146780
- 37 + 146743 = 146780
- 61 + 146719 = 146780
- 79 + 146701 = 146780
- 97 + 146683 = 146780
- 103 + 146677 = 146780
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 146,780 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 146780 first appears in π at position 363,152 of the decimal expansion (the 363,152ordinal-suffix:nd 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.
