Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494026, here are decompositions:

37 + 31493989 = 31494026
43 + 31493983 = 31494026
127 + 31493899 = 31494026
283 + 31493743 = 31494026
337 + 31493689 = 31494026
349 + 31493677 = 31494026
373 + 31493653 = 31494026
433 + 31493593 = 31494026

Showing the first eight; more decompositions exist.
