Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623674, here are decompositions:

3 + 31623671 = 31623674
7 + 31623667 = 31623674
67 + 31623607 = 31623674
151 + 31623523 = 31623674
163 + 31623511 = 31623674
193 + 31623481 = 31623674
331 + 31623343 = 31623674
337 + 31623337 = 31623674

Showing the first eight; more decompositions exist.
