Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604086, here are decompositions:

29 + 31604057 = 31604086
53 + 31604033 = 31604086
167 + 31603919 = 31604086
197 + 31603889 = 31604086
257 + 31603829 = 31604086
347 + 31603739 = 31604086
443 + 31603643 = 31604086
509 + 31603577 = 31604086

Showing the first eight; more decompositions exist.
