Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496650, here are decompositions:

83 + 31496567 = 31496650
113 + 31496537 = 31496650
131 + 31496519 = 31496650
233 + 31496417 = 31496650
281 + 31496369 = 31496650
389 + 31496261 = 31496650
431 + 31496219 = 31496650
509 + 31496141 = 31496650

Showing the first eight; more decompositions exist.
