Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998130, here are decompositions:
- 13 + 998117 = 998130
- 19 + 998111 = 998130
- 47 + 998083 = 998130
- 53 + 998077 = 998130
- 59 + 998071 = 998130
- 61 + 998069 = 998130
- 101 + 998029 = 998130
- 103 + 998027 = 998130
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 998,130 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 998130 first appears in π at position 553,473 of the decimal expansion (the 553,473ordinal-suffix:rd 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.
