Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496956, here are decompositions:

83 + 31496873 = 31496956
137 + 31496819 = 31496956
173 + 31496783 = 31496956
263 + 31496693 = 31496956
383 + 31496573 = 31496956
389 + 31496567 = 31496956
419 + 31496537 = 31496956
467 + 31496489 = 31496956

Showing the first eight; more decompositions exist.
