Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467342, here are decompositions:

13 + 31467329 = 31467342
31 + 31467311 = 31467342
41 + 31467301 = 31467342
83 + 31467259 = 31467342
113 + 31467229 = 31467342
139 + 31467203 = 31467342
173 + 31467169 = 31467342
239 + 31467103 = 31467342

Showing the first eight; more decompositions exist.
