Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604960, here are decompositions:

97 + 31604863 = 31604960
157 + 31604803 = 31604960
193 + 31604767 = 31604960
229 + 31604731 = 31604960
241 + 31604719 = 31604960
271 + 31604689 = 31604960
313 + 31604647 = 31604960
349 + 31604611 = 31604960

Showing the first eight; more decompositions exist.
