Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516762, here are decompositions:

5 + 31516757 = 31516762
59 + 31516703 = 31516762
131 + 31516631 = 31516762
149 + 31516613 = 31516762
191 + 31516571 = 31516762
239 + 31516523 = 31516762
269 + 31516493 = 31516762
293 + 31516469 = 31516762

Showing the first eight; more decompositions exist.
