Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619946, here are decompositions:

3 + 8619943 = 8619946
53 + 8619893 = 8619946
89 + 8619857 = 8619946
149 + 8619797 = 8619946
173 + 8619773 = 8619946
227 + 8619719 = 8619946
233 + 8619713 = 8619946
263 + 8619683 = 8619946

Showing the first eight; more decompositions exist.
