Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574954, here are decompositions:

43 + 31574911 = 31574954
67 + 31574887 = 31574954
181 + 31574773 = 31574954
277 + 31574677 = 31574954
283 + 31574671 = 31574954
457 + 31574497 = 31574954
487 + 31574467 = 31574954
751 + 31574203 = 31574954

Showing the first eight; more decompositions exist.
