Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164040, here are decompositions:
- 17 + 164023 = 164040
- 29 + 164011 = 164040
- 43 + 163997 = 164040
- 47 + 163993 = 164040
- 53 + 163987 = 164040
- 59 + 163981 = 164040
- 61 + 163979 = 164040
- 67 + 163973 = 164040
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 164,040 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 164040 first appears in π at position 188,272 of the decimal expansion (the 188,272ordinal-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.
