Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542356, here are decompositions:

127 + 31542229 = 31542356
193 + 31542163 = 31542356
367 + 31541989 = 31542356
379 + 31541977 = 31542356
457 + 31541899 = 31542356
463 + 31541893 = 31542356
487 + 31541869 = 31542356
499 + 31541857 = 31542356

Showing the first eight; more decompositions exist.
