Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496494, here are decompositions:

5 + 31496489 = 31496494
53 + 31496441 = 31496494
173 + 31496321 = 31496494
233 + 31496261 = 31496494
353 + 31496141 = 31496494
467 + 31496027 = 31496494
647 + 31495847 = 31496494
761 + 31495733 = 31496494

Showing the first eight; more decompositions exist.
