Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480268, here are decompositions:

67 + 31480201 = 31480268
139 + 31480129 = 31480268
151 + 31480117 = 31480268
307 + 31479961 = 31480268
439 + 31479829 = 31480268
499 + 31479769 = 31480268
571 + 31479697 = 31480268
619 + 31479649 = 31480268

Showing the first eight; more decompositions exist.
