Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604056, here are decompositions:

5 + 31604051 = 31604056
23 + 31604033 = 31604056
137 + 31603919 = 31604056
167 + 31603889 = 31604056
179 + 31603877 = 31604056
227 + 31603829 = 31604056
317 + 31603739 = 31604056
347 + 31603709 = 31604056

Showing the first eight; more decompositions exist.
