Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700648, here are decompositions:

59 + 8700589 = 8700648
67 + 8700581 = 8700648
101 + 8700547 = 8700648
109 + 8700539 = 8700648
127 + 8700521 = 8700648
137 + 8700511 = 8700648
181 + 8700467 = 8700648
191 + 8700457 = 8700648

Showing the first eight; more decompositions exist.
