Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947628, here are decompositions:

7 + 947621 = 947628
67 + 947561 = 947628
89 + 947539 = 947628
127 + 947501 = 947628
179 + 947449 = 947628
197 + 947431 = 947628
211 + 947417 = 947628
239 + 947389 = 947628

Showing the first eight; more decompositions exist.
