Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543076, here are decompositions:

7 + 31543069 = 31543076
67 + 31543009 = 31543076
109 + 31542967 = 31543076
127 + 31542949 = 31543076
139 + 31542937 = 31543076
199 + 31542877 = 31543076
277 + 31542799 = 31543076
349 + 31542727 = 31543076

Showing the first eight; more decompositions exist.
