Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543110, here are decompositions:

7 + 31543103 = 31543110
31 + 31543079 = 31543110
41 + 31543069 = 31543110
43 + 31543067 = 31543110
101 + 31543009 = 31543110
139 + 31542971 = 31543110
167 + 31542943 = 31543110
173 + 31542937 = 31543110

Showing the first eight; more decompositions exist.
