Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620744, here are decompositions:

5 + 8620739 = 8620744
17 + 8620727 = 8620744
23 + 8620721 = 8620744
53 + 8620691 = 8620744
71 + 8620673 = 8620744
107 + 8620637 = 8620744
113 + 8620631 = 8620744
173 + 8620571 = 8620744

Showing the first eight; more decompositions exist.
