Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130840, here are decompositions:
- 11 + 130829 = 130840
- 23 + 130817 = 130840
- 29 + 130811 = 130840
- 53 + 130787 = 130840
- 71 + 130769 = 130840
- 191 + 130649 = 130840
- 197 + 130643 = 130840
- 251 + 130589 = 130840
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 130,840 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 130840 first appears in π at position 130,005 of the decimal expansion (the 130,005ordinal-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.
