Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542602, here are decompositions:

43 + 31542559 = 31542602
79 + 31542523 = 31542602
163 + 31542439 = 31542602
211 + 31542391 = 31542602
229 + 31542373 = 31542602
373 + 31542229 = 31542602
439 + 31542163 = 31542602
499 + 31542103 = 31542602

Showing the first eight; more decompositions exist.
