Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644118, here are decompositions:

37 + 8644081 = 8644118
61 + 8644057 = 8644118
127 + 8643991 = 8644118
199 + 8643919 = 8644118
229 + 8643889 = 8644118
331 + 8643787 = 8644118
397 + 8643721 = 8644118
421 + 8643697 = 8644118

Showing the first eight; more decompositions exist.
