Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534996, here are decompositions:

83 + 31534913 = 31534996
197 + 31534799 = 31534996
239 + 31534757 = 31534996
257 + 31534739 = 31534996
359 + 31534637 = 31534996
443 + 31534553 = 31534996
503 + 31534493 = 31534996
509 + 31534487 = 31534996

Showing the first eight; more decompositions exist.
