Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543088, here are decompositions:

19 + 31543069 = 31543088
79 + 31543009 = 31543088
97 + 31542991 = 31543088
139 + 31542949 = 31543088
151 + 31542937 = 31543088
211 + 31542877 = 31543088
277 + 31542811 = 31543088
457 + 31542631 = 31543088

Showing the first eight; more decompositions exist.
