Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651742, here are decompositions:

5 + 8651737 = 8651742
19 + 8651723 = 8651742
31 + 8651711 = 8651742
53 + 8651689 = 8651742
59 + 8651683 = 8651742
79 + 8651663 = 8651742
103 + 8651639 = 8651742
139 + 8651603 = 8651742

Showing the first eight; more decompositions exist.
