Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543612, here are decompositions:

41 + 31543571 = 31543612
83 + 31543529 = 31543612
131 + 31543481 = 31543612
251 + 31543361 = 31543612
263 + 31543349 = 31543612
281 + 31543331 = 31543612
311 + 31543301 = 31543612
389 + 31543223 = 31543612

Showing the first eight; more decompositions exist.
