Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655248, here are decompositions:

31 + 8655217 = 8655248
37 + 8655211 = 8655248
211 + 8655037 = 8655248
241 + 8655007 = 8655248
307 + 8654941 = 8655248
331 + 8654917 = 8655248
409 + 8654839 = 8655248
439 + 8654809 = 8655248

Showing the first eight; more decompositions exist.
