Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624652, here are decompositions:

13 + 31624639 = 31624652
61 + 31624591 = 31624652
223 + 31624429 = 31624652
229 + 31624423 = 31624652
313 + 31624339 = 31624652
331 + 31624321 = 31624652
523 + 31624129 = 31624652
673 + 31623979 = 31624652

Showing the first eight; more decompositions exist.
