Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700630, here are decompositions:

31 + 8700599 = 8700630
41 + 8700589 = 8700630
67 + 8700563 = 8700630
83 + 8700547 = 8700630
101 + 8700529 = 8700630
109 + 8700521 = 8700630
157 + 8700473 = 8700630
163 + 8700467 = 8700630

Showing the first eight; more decompositions exist.
