Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472774, here are decompositions:

163 + 31472611 = 31472774
337 + 31472437 = 31472774
607 + 31472167 = 31472774
631 + 31472143 = 31472774
643 + 31472131 = 31472774
733 + 31472041 = 31472774
1063 + 31471711 = 31472774
1093 + 31471681 = 31472774

Showing the first eight; more decompositions exist.
