Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947620, here are decompositions:

17 + 947603 = 947620
41 + 947579 = 947620
59 + 947561 = 947620
137 + 947483 = 947620
197 + 947423 = 947620
239 + 947381 = 947620
251 + 947369 = 947620
263 + 947357 = 947620

Showing the first eight; more decompositions exist.
