Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496628, here are decompositions:

17 + 31496611 = 31496628
29 + 31496599 = 31496628
41 + 31496587 = 31496628
61 + 31496567 = 31496628
89 + 31496539 = 31496628
109 + 31496519 = 31496628
139 + 31496489 = 31496628
179 + 31496449 = 31496628

Showing the first eight; more decompositions exist.
