Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672942, here are decompositions:

73 + 8672869 = 8672942
151 + 8672791 = 8672942
163 + 8672779 = 8672942
211 + 8672731 = 8672942
283 + 8672659 = 8672942
379 + 8672563 = 8672942
433 + 8672509 = 8672942
739 + 8672203 = 8672942

Showing the first eight; more decompositions exist.
