Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624780, here are decompositions:

7 + 8624773 = 8624780
67 + 8624713 = 8624780
103 + 8624677 = 8624780
163 + 8624617 = 8624780
181 + 8624599 = 8624780
277 + 8624503 = 8624780
331 + 8624449 = 8624780
397 + 8624383 = 8624780

Showing the first eight; more decompositions exist.
