Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618514, here are decompositions:

73 + 31618441 = 31618514
283 + 31618231 = 31618514
457 + 31618057 = 31618514
547 + 31617967 = 31618514
643 + 31617871 = 31618514
661 + 31617853 = 31618514
751 + 31617763 = 31618514
757 + 31617757 = 31618514

Showing the first eight; more decompositions exist.
