Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523586, here are decompositions:

7 + 31523579 = 31523586
47 + 31523539 = 31523586
109 + 31523477 = 31523586
113 + 31523473 = 31523586
167 + 31523419 = 31523586
179 + 31523407 = 31523586
239 + 31523347 = 31523586
257 + 31523329 = 31523586

Showing the first eight; more decompositions exist.
