Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493414, here are decompositions:

37 + 31493377 = 31493414
61 + 31493353 = 31493414
67 + 31493347 = 31493414
163 + 31493251 = 31493414
223 + 31493191 = 31493414
283 + 31493131 = 31493414
331 + 31493083 = 31493414
367 + 31493047 = 31493414

Showing the first eight; more decompositions exist.
