Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499932, here are decompositions:

11 + 31499921 = 31499932
89 + 31499843 = 31499932
311 + 31499621 = 31499932
521 + 31499411 = 31499932
641 + 31499291 = 31499932
701 + 31499231 = 31499932
743 + 31499189 = 31499932
773 + 31499159 = 31499932

Showing the first eight; more decompositions exist.
