Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655722, here are decompositions:

3 + 8655719 = 8655722
43 + 8655679 = 8655722
73 + 8655649 = 8655722
373 + 8655349 = 8655722
379 + 8655343 = 8655722
409 + 8655313 = 8655722
463 + 8655259 = 8655722
619 + 8655103 = 8655722

Showing the first eight; more decompositions exist.
