Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656730, here are decompositions:

3 + 8656727 = 8656730
127 + 8656603 = 8656730
157 + 8656573 = 8656730
193 + 8656537 = 8656730
307 + 8656423 = 8656730
331 + 8656399 = 8656730
337 + 8656393 = 8656730
367 + 8656363 = 8656730

Showing the first eight; more decompositions exist.
