Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496758, here are decompositions:

17 + 31496741 = 31496758
89 + 31496669 = 31496758
191 + 31496567 = 31496758
239 + 31496519 = 31496758
269 + 31496489 = 31496758
317 + 31496441 = 31496758
389 + 31496369 = 31496758
617 + 31496141 = 31496758

Showing the first eight; more decompositions exist.
