Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574774, here are decompositions:

73 + 31574701 = 31574774
97 + 31574677 = 31574774
103 + 31574671 = 31574774
211 + 31574563 = 31574774
277 + 31574497 = 31574774
307 + 31574467 = 31574774
331 + 31574443 = 31574774
337 + 31574437 = 31574774

Showing the first eight; more decompositions exist.
