Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673242, here are decompositions:

43 + 8673199 = 8673242
223 + 8673019 = 8673242
373 + 8672869 = 8673242
421 + 8672821 = 8673242
463 + 8672779 = 8673242
601 + 8672641 = 8673242
691 + 8672551 = 8673242
733 + 8672509 = 8673242

Showing the first eight; more decompositions exist.
