Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670636, here are decompositions:

17 + 8670619 = 8670636
47 + 8670589 = 8670636
53 + 8670583 = 8670636
83 + 8670553 = 8670636
103 + 8670533 = 8670636
113 + 8670523 = 8670636
127 + 8670509 = 8670636
137 + 8670499 = 8670636

Showing the first eight; more decompositions exist.
