Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567586, here are decompositions:

73 + 31567513 = 31567586
157 + 31567429 = 31567586
307 + 31567279 = 31567586
367 + 31567219 = 31567586
373 + 31567213 = 31567586
433 + 31567153 = 31567586
499 + 31567087 = 31567586
607 + 31566979 = 31567586

Showing the first eight; more decompositions exist.
