Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480274, here are decompositions:

73 + 31480201 = 31480274
157 + 31480117 = 31480274
313 + 31479961 = 31480274
457 + 31479817 = 31480274
577 + 31479697 = 31480274
733 + 31479541 = 31480274
757 + 31479517 = 31480274
853 + 31479421 = 31480274

Showing the first eight; more decompositions exist.
