Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623576, here are decompositions:

53 + 31623523 = 31623576
67 + 31623509 = 31623576
79 + 31623497 = 31623576
97 + 31623479 = 31623576
137 + 31623439 = 31623576
199 + 31623377 = 31623576
233 + 31623343 = 31623576
239 + 31623337 = 31623576

Showing the first eight; more decompositions exist.
