Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496800, here are decompositions:

17 + 31496783 = 31496800
59 + 31496741 = 31496800
107 + 31496693 = 31496800
131 + 31496669 = 31496800
227 + 31496573 = 31496800
233 + 31496567 = 31496800
263 + 31496537 = 31496800
281 + 31496519 = 31496800

Showing the first eight; more decompositions exist.
