Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467718, here are decompositions:

41 + 31467677 = 31467718
71 + 31467647 = 31467718
131 + 31467587 = 31467718
167 + 31467551 = 31467718
179 + 31467539 = 31467718
251 + 31467467 = 31467718
281 + 31467437 = 31467718
389 + 31467329 = 31467718

Showing the first eight; more decompositions exist.
