Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656370, here are decompositions:

3 + 8656367 = 8656370
7 + 8656363 = 8656370
13 + 8656357 = 8656370
31 + 8656339 = 8656370
97 + 8656273 = 8656370
139 + 8656231 = 8656370
181 + 8656189 = 8656370
193 + 8656177 = 8656370

Showing the first eight; more decompositions exist.
