Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621512, here are decompositions:

59 + 8621453 = 8621512
83 + 8621429 = 8621512
101 + 8621411 = 8621512
173 + 8621339 = 8621512
269 + 8621243 = 8621512
311 + 8621201 = 8621512
359 + 8621153 = 8621512
461 + 8621051 = 8621512

Showing the first eight; more decompositions exist.
