Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480076, here are decompositions:

127 + 31479949 = 31480076
283 + 31479793 = 31480076
307 + 31479769 = 31480076
337 + 31479739 = 31480076
379 + 31479697 = 31480076
457 + 31479619 = 31480076
487 + 31479589 = 31480076
499 + 31479577 = 31480076

Showing the first eight; more decompositions exist.
