Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655230, here are decompositions:

13 + 8655217 = 8655230
19 + 8655211 = 8655230
127 + 8655103 = 8655230
193 + 8655037 = 8655230
223 + 8655007 = 8655230
271 + 8654959 = 8655230
313 + 8654917 = 8655230
421 + 8654809 = 8655230

Showing the first eight; more decompositions exist.
