Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543082, here are decompositions:

3 + 31543079 = 31543082
13 + 31543069 = 31543082
73 + 31543009 = 31543082
139 + 31542943 = 31543082
271 + 31542811 = 31543082
283 + 31542799 = 31543082
379 + 31542703 = 31543082
523 + 31542559 = 31543082

Showing the first eight; more decompositions exist.
