Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655874, here are decompositions:

5 + 8655869 = 8655874
113 + 8655761 = 8655874
167 + 8655707 = 8655874
173 + 8655701 = 8655874
197 + 8655677 = 8655874
233 + 8655641 = 8655874
251 + 8655623 = 8655874
263 + 8655611 = 8655874

Showing the first eight; more decompositions exist.
