Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528782, here are decompositions:

31 + 31528751 = 31528782
41 + 31528741 = 31528782
53 + 31528729 = 31528782
59 + 31528723 = 31528782
113 + 31528669 = 31528782
149 + 31528633 = 31528782
223 + 31528559 = 31528782
251 + 31528531 = 31528782

Showing the first eight; more decompositions exist.
