Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672866, here are decompositions:

5 + 8672861 = 8672866
47 + 8672819 = 8672866
179 + 8672687 = 8672866
227 + 8672639 = 8672866
269 + 8672597 = 8672866
347 + 8672519 = 8672866
353 + 8672513 = 8672866
383 + 8672483 = 8672866

Showing the first eight; more decompositions exist.
