Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542266, here are decompositions:

37 + 31542229 = 31542266
103 + 31542163 = 31542266
163 + 31542103 = 31542266
199 + 31542067 = 31542266
229 + 31542037 = 31542266
277 + 31541989 = 31542266
367 + 31541899 = 31542266
373 + 31541893 = 31542266

Showing the first eight; more decompositions exist.
