Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615654, here are decompositions:

3 + 31615651 = 31615654
71 + 31615583 = 31615654
251 + 31615403 = 31615654
263 + 31615391 = 31615654
311 + 31615343 = 31615654
443 + 31615211 = 31615654
461 + 31615193 = 31615654
467 + 31615187 = 31615654

Showing the first eight; more decompositions exist.
