Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496806, here are decompositions:

23 + 31496783 = 31496806
113 + 31496693 = 31496806
137 + 31496669 = 31496806
233 + 31496573 = 31496806
239 + 31496567 = 31496806
269 + 31496537 = 31496806
317 + 31496489 = 31496806
389 + 31496417 = 31496806

Showing the first eight; more decompositions exist.
