Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606778, here are decompositions:

41 + 8606737 = 8606778
157 + 8606621 = 8606778
179 + 8606599 = 8606778
241 + 8606537 = 8606778
251 + 8606527 = 8606778
269 + 8606509 = 8606778
277 + 8606501 = 8606778
331 + 8606447 = 8606778

Showing the first eight; more decompositions exist.
