Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604948, here are decompositions:

181 + 31604767 = 31604948
229 + 31604719 = 31604948
307 + 31604641 = 31604948
337 + 31604611 = 31604948
439 + 31604509 = 31604948
577 + 31604371 = 31604948
601 + 31604347 = 31604948
607 + 31604341 = 31604948

Showing the first eight; more decompositions exist.
