Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656142, here are decompositions:

13 + 8656129 = 8656142
73 + 8656069 = 8656142
109 + 8656033 = 8656142
151 + 8655991 = 8656142
223 + 8655919 = 8656142
241 + 8655901 = 8656142
283 + 8655859 = 8656142
373 + 8655769 = 8656142

Showing the first eight; more decompositions exist.
