Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574718, here are decompositions:

17 + 31574701 = 31574718
29 + 31574689 = 31574718
31 + 31574687 = 31574718
37 + 31574681 = 31574718
41 + 31574677 = 31574718
47 + 31574671 = 31574718
61 + 31574657 = 31574718
79 + 31574639 = 31574718

Showing the first eight; more decompositions exist.
