Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630782, here are decompositions:

3 + 8630779 = 8630782
11 + 8630771 = 8630782
23 + 8630759 = 8630782
113 + 8630669 = 8630782
191 + 8630591 = 8630782
263 + 8630519 = 8630782
491 + 8630291 = 8630782
821 + 8629961 = 8630782

Showing the first eight; more decompositions exist.
