Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480376, here are decompositions:

3 + 31480373 = 31480376
7 + 31480369 = 31480376
547 + 31479829 = 31480376
607 + 31479769 = 31480376
619 + 31479757 = 31480376
727 + 31479649 = 31480376
757 + 31479619 = 31480376
787 + 31479589 = 31480376

Showing the first eight; more decompositions exist.
