Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508576, here are decompositions:

7 + 31508569 = 31508576
19 + 31508557 = 31508576
67 + 31508509 = 31508576
349 + 31508227 = 31508576
373 + 31508203 = 31508576
397 + 31508179 = 31508576
433 + 31508143 = 31508576
457 + 31508119 = 31508576

Showing the first eight; more decompositions exist.
