Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496532, here are decompositions:

13 + 31496519 = 31496532
43 + 31496489 = 31496532
83 + 31496449 = 31496532
103 + 31496429 = 31496532
113 + 31496419 = 31496532
163 + 31496369 = 31496532
211 + 31496321 = 31496532
239 + 31496293 = 31496532

Showing the first eight; more decompositions exist.
