Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543046, here are decompositions:

37 + 31543009 = 31543046
79 + 31542967 = 31543046
97 + 31542949 = 31543046
103 + 31542943 = 31543046
109 + 31542937 = 31543046
349 + 31542697 = 31543046
433 + 31542613 = 31543046
487 + 31542559 = 31543046

Showing the first eight; more decompositions exist.
