Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574586, here are decompositions:

23 + 31574563 = 31574586
79 + 31574507 = 31574586
89 + 31574497 = 31574586
97 + 31574489 = 31574586
107 + 31574479 = 31574586
137 + 31574449 = 31574586
149 + 31574437 = 31574586
157 + 31574429 = 31574586

Showing the first eight; more decompositions exist.
