Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567358, here are decompositions:

61 + 31567297 = 31567358
79 + 31567279 = 31567358
127 + 31567231 = 31567358
139 + 31567219 = 31567358
271 + 31567087 = 31567358
379 + 31566979 = 31567358
439 + 31566919 = 31567358
457 + 31566901 = 31567358

Showing the first eight; more decompositions exist.
