Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604422, here are decompositions:

233 + 31604189 = 31604422
293 + 31604129 = 31604422
389 + 31604033 = 31604422
431 + 31603991 = 31604422
491 + 31603931 = 31604422
503 + 31603919 = 31604422
593 + 31603829 = 31604422
683 + 31603739 = 31604422

Showing the first eight; more decompositions exist.
