Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496854, here are decompositions:

71 + 31496783 = 31496854
113 + 31496741 = 31496854
281 + 31496573 = 31496854
317 + 31496537 = 31496854
593 + 31496261 = 31496854
797 + 31496057 = 31496854
827 + 31496027 = 31496854
1097 + 31495757 = 31496854

Showing the first eight; more decompositions exist.
