Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543136, here are decompositions:

3 + 31543133 = 31543136
67 + 31543069 = 31543136
127 + 31543009 = 31543136
193 + 31542943 = 31543136
199 + 31542937 = 31543136
307 + 31542829 = 31543136
337 + 31542799 = 31543136
349 + 31542787 = 31543136

Showing the first eight; more decompositions exist.
