Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496658, here are decompositions:

47 + 31496611 = 31496658
59 + 31496599 = 31496658
71 + 31496587 = 31496658
107 + 31496551 = 31496658
139 + 31496519 = 31496658
229 + 31496429 = 31496658
239 + 31496419 = 31496658
241 + 31496417 = 31496658

Showing the first eight; more decompositions exist.
