Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542282, here are decompositions:

53 + 31542229 = 31542282
179 + 31542103 = 31542282
199 + 31542083 = 31542282
251 + 31542031 = 31542282
269 + 31542013 = 31542282
271 + 31542011 = 31542282
281 + 31542001 = 31542282
293 + 31541989 = 31542282

Showing the first eight; more decompositions exist.
