Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499824, here are decompositions:

113 + 31499711 = 31499824
263 + 31499561 = 31499824
557 + 31499267 = 31499824
593 + 31499231 = 31499824
641 + 31499183 = 31499824
761 + 31499063 = 31499824
821 + 31499003 = 31499824
857 + 31498967 = 31499824

Showing the first eight; more decompositions exist.
