Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493944, here are decompositions:

3 + 31493941 = 31493944
17 + 31493927 = 31493944
227 + 31493717 = 31493944
233 + 31493711 = 31493944
431 + 31493513 = 31493944
467 + 31493477 = 31493944
653 + 31493291 = 31493944
743 + 31493201 = 31493944

Showing the first eight; more decompositions exist.
