Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567584, here are decompositions:

31 + 31567553 = 31567584
71 + 31567513 = 31567584
73 + 31567511 = 31567584
157 + 31567427 = 31567584
173 + 31567411 = 31567584
271 + 31567313 = 31567584
313 + 31567271 = 31567584
317 + 31567267 = 31567584

Showing the first eight; more decompositions exist.
