Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673812, here are decompositions:

31 + 8673781 = 8673812
109 + 8673703 = 8673812
211 + 8673601 = 8673812
241 + 8673571 = 8673812
313 + 8673499 = 8673812
349 + 8673463 = 8673812
379 + 8673433 = 8673812
439 + 8673373 = 8673812

Showing the first eight; more decompositions exist.
