Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619862, here are decompositions:

3 + 8619859 = 8619862
5 + 8619857 = 8619862
71 + 8619791 = 8619862
89 + 8619773 = 8619862
149 + 8619713 = 8619862
179 + 8619683 = 8619862
239 + 8619623 = 8619862
269 + 8619593 = 8619862

Showing the first eight; more decompositions exist.
