Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534666, here are decompositions:

29 + 31534637 = 31534666
113 + 31534553 = 31534666
173 + 31534493 = 31534666
179 + 31534487 = 31534666
239 + 31534427 = 31534666
419 + 31534247 = 31534666
467 + 31534199 = 31534666
479 + 31534187 = 31534666

Showing the first eight; more decompositions exist.
