Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542314, here are decompositions:

151 + 31542163 = 31542314
211 + 31542103 = 31542314
277 + 31542037 = 31542314
283 + 31542031 = 31542314
313 + 31542001 = 31542314
337 + 31541977 = 31542314
421 + 31541893 = 31542314
457 + 31541857 = 31542314

Showing the first eight; more decompositions exist.
