Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621650, here are decompositions:

41 + 8621609 = 8621650
173 + 8621477 = 8621650
197 + 8621453 = 8621650
239 + 8621411 = 8621650
311 + 8621339 = 8621650
449 + 8621201 = 8621650
461 + 8621189 = 8621650
467 + 8621183 = 8621650

Showing the first eight; more decompositions exist.
