Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756658, here are decompositions:

5 + 8756653 = 8756658
67 + 8756591 = 8756658
101 + 8756557 = 8756658
107 + 8756551 = 8756658
139 + 8756519 = 8756658
149 + 8756509 = 8756658
151 + 8756507 = 8756658
199 + 8756459 = 8756658

Showing the first eight; more decompositions exist.
