Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542296, here are decompositions:

67 + 31542229 = 31542296
193 + 31542103 = 31542296
229 + 31542067 = 31542296
283 + 31542013 = 31542296
307 + 31541989 = 31542296
397 + 31541899 = 31542296
439 + 31541857 = 31542296
619 + 31541677 = 31542296

Showing the first eight; more decompositions exist.
