Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657242, here are decompositions:

3 + 8657239 = 8657242
5 + 8657237 = 8657242
131 + 8657111 = 8657242
173 + 8657069 = 8657242
233 + 8657009 = 8657242
263 + 8656979 = 8657242
509 + 8656733 = 8657242
521 + 8656721 = 8657242

Showing the first eight; more decompositions exist.
