Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684388, here are decompositions:
- 29 + 8684359 = 8684388
- 47 + 8684341 = 8684388
- 59 + 8684329 = 8684388
- 109 + 8684279 = 8684388
- 127 + 8684261 = 8684388
- 131 + 8684257 = 8684388
- 157 + 8684231 = 8684388
- 199 + 8684189 = 8684388
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 8,684,388 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
