Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543104, here are decompositions:

37 + 31543067 = 31543104
113 + 31542991 = 31543104
137 + 31542967 = 31543104
163 + 31542941 = 31543104
167 + 31542937 = 31543104
193 + 31542911 = 31543104
223 + 31542881 = 31543104
227 + 31542877 = 31543104

Showing the first eight; more decompositions exist.
