Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493984, here are decompositions:

43 + 31493941 = 31493984
103 + 31493881 = 31493984
127 + 31493857 = 31493984
163 + 31493821 = 31493984
241 + 31493743 = 31493984
307 + 31493677 = 31493984
331 + 31493653 = 31493984
373 + 31493611 = 31493984

Showing the first eight; more decompositions exist.
