Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476342, here are decompositions:

59 + 31476283 = 31476342
103 + 31476239 = 31476342
173 + 31476169 = 31476342
193 + 31476149 = 31476342
199 + 31476143 = 31476342
223 + 31476119 = 31476342
229 + 31476113 = 31476342
269 + 31476073 = 31476342

Showing the first eight; more decompositions exist.
