Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476586, here are decompositions:

137 + 31476449 = 31476586
149 + 31476437 = 31476586
173 + 31476413 = 31476586
233 + 31476353 = 31476586
269 + 31476317 = 31476586
347 + 31476239 = 31476586
443 + 31476143 = 31476586
467 + 31476119 = 31476586

Showing the first eight; more decompositions exist.
