Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656738, here are decompositions:

5 + 8656733 = 8656738
11 + 8656727 = 8656738
17 + 8656721 = 8656738
47 + 8656691 = 8656738
71 + 8656667 = 8656738
149 + 8656589 = 8656738
191 + 8656547 = 8656738
227 + 8656511 = 8656738

Showing the first eight; more decompositions exist.
