Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496998, here are decompositions:

41 + 31496957 = 31496998
179 + 31496819 = 31496998
257 + 31496741 = 31496998
431 + 31496567 = 31496998
461 + 31496537 = 31496998
479 + 31496519 = 31496998
509 + 31496489 = 31496998
557 + 31496441 = 31496998

Showing the first eight; more decompositions exist.
