Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493594, here are decompositions:

37 + 31493557 = 31493594
61 + 31493533 = 31493594
73 + 31493521 = 31493594
127 + 31493467 = 31493594
151 + 31493443 = 31493594
241 + 31493353 = 31493594
271 + 31493323 = 31493594
463 + 31493131 = 31493594

Showing the first eight; more decompositions exist.
