Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497196, here are decompositions:

113 + 31497083 = 31497196
233 + 31496963 = 31497196
239 + 31496957 = 31497196
503 + 31496693 = 31497196
659 + 31496537 = 31497196
677 + 31496519 = 31497196
827 + 31496369 = 31497196
977 + 31496219 = 31497196

Showing the first eight; more decompositions exist.
