Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644088, here are decompositions:

7 + 8644081 = 8644088
31 + 8644057 = 8644088
97 + 8643991 = 8644088
199 + 8643889 = 8644088
331 + 8643757 = 8644088
367 + 8643721 = 8644088
457 + 8643631 = 8644088
499 + 8643589 = 8644088

Showing the first eight; more decompositions exist.
