Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574714, here are decompositions:

13 + 31574701 = 31574714
37 + 31574677 = 31574714
43 + 31574671 = 31574714
151 + 31574563 = 31574714
271 + 31574443 = 31574714
277 + 31574437 = 31574714
541 + 31574173 = 31574714
607 + 31574107 = 31574714

Showing the first eight; more decompositions exist.
