Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496652, here are decompositions:

41 + 31496611 = 31496652
53 + 31496599 = 31496652
59 + 31496593 = 31496652
79 + 31496573 = 31496652
101 + 31496551 = 31496652
113 + 31496539 = 31496652
163 + 31496489 = 31496652
211 + 31496441 = 31496652

Showing the first eight; more decompositions exist.
