Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679242, here are decompositions:

43 + 8679199 = 8679242
163 + 8679079 = 8679242
349 + 8678893 = 8679242
379 + 8678863 = 8679242
409 + 8678833 = 8679242
421 + 8678821 = 8679242
463 + 8678779 = 8679242
541 + 8678701 = 8679242

Showing the first eight; more decompositions exist.
