Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480196, here are decompositions:

67 + 31480129 = 31480196
79 + 31480117 = 31480196
367 + 31479829 = 31480196
379 + 31479817 = 31480196
439 + 31479757 = 31480196
457 + 31479739 = 31480196
499 + 31479697 = 31480196
547 + 31479649 = 31480196

Showing the first eight; more decompositions exist.
