Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528996, here are decompositions:

3 + 31528993 = 31528996
29 + 31528967 = 31528996
173 + 31528823 = 31528996
383 + 31528613 = 31528996
449 + 31528547 = 31528996
563 + 31528433 = 31528996
647 + 31528349 = 31528996
659 + 31528337 = 31528996

Showing the first eight; more decompositions exist.
