Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642612, here are decompositions:

31 + 8642581 = 8642612
79 + 8642533 = 8642612
103 + 8642509 = 8642612
163 + 8642449 = 8642612
229 + 8642383 = 8642612
283 + 8642329 = 8642612
331 + 8642281 = 8642612
439 + 8642173 = 8642612

Showing the first eight; more decompositions exist.
