Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494700, here are decompositions:

11 + 31494689 = 31494700
89 + 31494611 = 31494700
191 + 31494509 = 31494700
197 + 31494503 = 31494700
233 + 31494467 = 31494700
257 + 31494443 = 31494700
269 + 31494431 = 31494700
311 + 31494389 = 31494700

Showing the first eight; more decompositions exist.
