Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629312, here are decompositions:

71 + 8629241 = 8629312
113 + 8629199 = 8629312
173 + 8629139 = 8629312
233 + 8629079 = 8629312
239 + 8629073 = 8629312
389 + 8628923 = 8629312
521 + 8628791 = 8629312
683 + 8628629 = 8629312

Showing the first eight; more decompositions exist.
