Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 134820, here are decompositions:
- 13 + 134807 = 134820
- 31 + 134789 = 134820
- 43 + 134777 = 134820
- 67 + 134753 = 134820
- 79 + 134741 = 134820
- 89 + 134731 = 134820
- 113 + 134707 = 134820
- 137 + 134683 = 134820
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 134,820 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 134820 first appears in π at position 179,587 of the decimal expansion (the 179,587ordinal-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.
