Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655748, here are decompositions:

29 + 8655719 = 8655748
41 + 8655707 = 8655748
47 + 8655701 = 8655748
71 + 8655677 = 8655748
107 + 8655641 = 8655748
137 + 8655611 = 8655748
251 + 8655497 = 8655748
347 + 8655401 = 8655748

Showing the first eight; more decompositions exist.
