Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523662, here are decompositions:

3 + 31523659 = 31523662
11 + 31523651 = 31523662
29 + 31523633 = 31523662
83 + 31523579 = 31523662
251 + 31523411 = 31523662
263 + 31523399 = 31523662
281 + 31523381 = 31523662
353 + 31523309 = 31523662

Showing the first eight; more decompositions exist.
