Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542914, here are decompositions:

3 + 31542911 = 31542914
37 + 31542877 = 31542914
103 + 31542811 = 31542914
127 + 31542787 = 31542914
211 + 31542703 = 31542914
283 + 31542631 = 31542914
367 + 31542547 = 31542914
457 + 31542457 = 31542914

Showing the first eight; more decompositions exist.
