Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655742, here are decompositions:

3 + 8655739 = 8655742
23 + 8655719 = 8655742
41 + 8655701 = 8655742
71 + 8655671 = 8655742
89 + 8655653 = 8655742
101 + 8655641 = 8655742
113 + 8655629 = 8655742
131 + 8655611 = 8655742

Showing the first eight; more decompositions exist.
