Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642798, here are decompositions:

37 + 8642761 = 8642798
331 + 8642467 = 8642798
349 + 8642449 = 8642798
601 + 8642197 = 8642798
691 + 8642107 = 8642798
739 + 8642059 = 8642798
811 + 8641987 = 8642798
907 + 8641891 = 8642798

Showing the first eight; more decompositions exist.
