Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496724, here are decompositions:

5 + 31496719 = 31496724
31 + 31496693 = 31496724
47 + 31496677 = 31496724
53 + 31496671 = 31496724
113 + 31496611 = 31496724
131 + 31496593 = 31496724
137 + 31496587 = 31496724
151 + 31496573 = 31496724

Showing the first eight; more decompositions exist.
