Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556674, here are decompositions:

137 + 31556537 = 31556674
173 + 31556501 = 31556674
197 + 31556477 = 31556674
251 + 31556423 = 31556674
257 + 31556417 = 31556674
293 + 31556381 = 31556674
431 + 31556243 = 31556674
593 + 31556081 = 31556674

Showing the first eight; more decompositions exist.
