Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496776, here are decompositions:

83 + 31496693 = 31496776
107 + 31496669 = 31496776
239 + 31496537 = 31496776
257 + 31496519 = 31496776
347 + 31496429 = 31496776
359 + 31496417 = 31496776
557 + 31496219 = 31496776
653 + 31496123 = 31496776

Showing the first eight; more decompositions exist.
