Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480364, here are decompositions:

163 + 31480201 = 31480364
547 + 31479817 = 31480364
571 + 31479793 = 31480364
607 + 31479757 = 31480364
787 + 31479577 = 31480364
823 + 31479541 = 31480364
907 + 31479457 = 31480364
1087 + 31479277 = 31480364

Showing the first eight; more decompositions exist.
