Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619724, here are decompositions:

5 + 8619719 = 8619724
11 + 8619713 = 8619724
41 + 8619683 = 8619724
101 + 8619623 = 8619724
131 + 8619593 = 8619724
137 + 8619587 = 8619724
173 + 8619551 = 8619724
233 + 8619491 = 8619724

Showing the first eight; more decompositions exist.
