Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496908, here are decompositions:

89 + 31496819 = 31496908
167 + 31496741 = 31496908
239 + 31496669 = 31496908
389 + 31496519 = 31496908
419 + 31496489 = 31496908
467 + 31496441 = 31496908
479 + 31496429 = 31496908
491 + 31496417 = 31496908

Showing the first eight; more decompositions exist.
