Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543528, here are decompositions:

47 + 31543481 = 31543528
131 + 31543397 = 31543528
167 + 31543361 = 31543528
179 + 31543349 = 31543528
197 + 31543331 = 31543528
227 + 31543301 = 31543528
311 + 31543217 = 31543528
347 + 31543181 = 31543528

Showing the first eight; more decompositions exist.
