Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528076, here are decompositions:

7 + 31528069 = 31528076
79 + 31527997 = 31528076
109 + 31527967 = 31528076
163 + 31527913 = 31528076
367 + 31527709 = 31528076
373 + 31527703 = 31528076
379 + 31527697 = 31528076
499 + 31527577 = 31528076

Showing the first eight; more decompositions exist.
