Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658242, here are decompositions:

139 + 8658103 = 8658242
199 + 8658043 = 8658242
409 + 8657833 = 8658242
613 + 8657629 = 8658242
631 + 8657611 = 8658242
673 + 8657569 = 8658242
709 + 8657533 = 8658242
739 + 8657503 = 8658242

Showing the first eight; more decompositions exist.
