Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619742, here are decompositions:

23 + 8619719 = 8619742
29 + 8619713 = 8619742
59 + 8619683 = 8619742
149 + 8619593 = 8619742
191 + 8619551 = 8619742
233 + 8619509 = 8619742
251 + 8619491 = 8619742
269 + 8619473 = 8619742

Showing the first eight; more decompositions exist.
