Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624722, here are decompositions:

5 + 8624717 = 8624722
53 + 8624669 = 8624722
89 + 8624633 = 8624722
101 + 8624621 = 8624722
149 + 8624573 = 8624722
263 + 8624459 = 8624722
479 + 8624243 = 8624722
521 + 8624201 = 8624722

Showing the first eight; more decompositions exist.
