Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655624, here are decompositions:

13 + 8655611 = 8655624
97 + 8655527 = 8655624
127 + 8655497 = 8655624
167 + 8655457 = 8655624
191 + 8655433 = 8655624
223 + 8655401 = 8655624
281 + 8655343 = 8655624
293 + 8655331 = 8655624

Showing the first eight; more decompositions exist.
