Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990340, here are decompositions:
- 11 + 990329 = 990340
- 17 + 990323 = 990340
- 47 + 990293 = 990340
- 53 + 990287 = 990340
- 59 + 990281 = 990340
- 101 + 990239 = 990340
- 317 + 990023 = 990340
- 359 + 989981 = 990340
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 990,340 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 990340 first appears in π at position 398,300 of the decimal expansion (the 398,300ordinal-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.
