Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604768, here are decompositions:

37 + 31604731 = 31604768
79 + 31604689 = 31604768
127 + 31604641 = 31604768
157 + 31604611 = 31604768
211 + 31604557 = 31604768
271 + 31604497 = 31604768
397 + 31604371 = 31604768
409 + 31604359 = 31604768

Showing the first eight; more decompositions exist.
