Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657742, here are decompositions:

11 + 8657731 = 8657742
19 + 8657723 = 8657742
43 + 8657699 = 8657742
61 + 8657681 = 8657742
103 + 8657639 = 8657742
109 + 8657633 = 8657742
113 + 8657629 = 8657742
131 + 8657611 = 8657742

Showing the first eight; more decompositions exist.
