Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655844, here are decompositions:

3 + 8655841 = 8655844
83 + 8655761 = 8655844
137 + 8655707 = 8655844
167 + 8655677 = 8655844
173 + 8655671 = 8655844
191 + 8655653 = 8655844
233 + 8655611 = 8655844
317 + 8655527 = 8655844

Showing the first eight; more decompositions exist.
