Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629408, here are decompositions:

59 + 8629349 = 8629408
167 + 8629241 = 8629408
239 + 8629169 = 8629408
251 + 8629157 = 8629408
269 + 8629139 = 8629408
509 + 8628899 = 8629408
617 + 8628791 = 8629408
761 + 8628647 = 8629408

Showing the first eight; more decompositions exist.
