Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543208, here are decompositions:

139 + 31543069 = 31543208
199 + 31543009 = 31543208
241 + 31542967 = 31543208
271 + 31542937 = 31543208
331 + 31542877 = 31543208
379 + 31542829 = 31543208
397 + 31542811 = 31543208
409 + 31542799 = 31543208

Showing the first eight; more decompositions exist.
