Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496782, here are decompositions:

3 + 31496779 = 31496782
41 + 31496741 = 31496782
89 + 31496693 = 31496782
113 + 31496669 = 31496782
263 + 31496519 = 31496782
293 + 31496489 = 31496782
353 + 31496429 = 31496782
461 + 31496321 = 31496782

Showing the first eight; more decompositions exist.
