Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657418, here are decompositions:

31 + 8657387 = 8657418
37 + 8657381 = 8657418
41 + 8657377 = 8657418
61 + 8657357 = 8657418
109 + 8657309 = 8657418
127 + 8657291 = 8657418
179 + 8657239 = 8657418
181 + 8657237 = 8657418

Showing the first eight; more decompositions exist.
