Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655042, here are decompositions:

5 + 8655037 = 8655042
13 + 8655029 = 8655042
31 + 8655011 = 8655042
61 + 8654981 = 8655042
83 + 8654959 = 8655042
101 + 8654941 = 8655042
233 + 8654809 = 8655042
239 + 8654803 = 8655042

Showing the first eight; more decompositions exist.
