Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496608, here are decompositions:

41 + 31496567 = 31496608
71 + 31496537 = 31496608
89 + 31496519 = 31496608
167 + 31496441 = 31496608
179 + 31496429 = 31496608
191 + 31496417 = 31496608
239 + 31496369 = 31496608
347 + 31496261 = 31496608

Showing the first eight; more decompositions exist.
