Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656130, here are decompositions:

13 + 8656117 = 8656130
37 + 8656093 = 8656130
61 + 8656069 = 8656130
73 + 8656057 = 8656130
97 + 8656033 = 8656130
139 + 8655991 = 8656130
163 + 8655967 = 8656130
193 + 8655937 = 8656130

Showing the first eight; more decompositions exist.
