Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668510, here are decompositions:

89 + 8668421 = 8668510
107 + 8668403 = 8668510
131 + 8668379 = 8668510
317 + 8668193 = 8668510
353 + 8668157 = 8668510
359 + 8668151 = 8668510
443 + 8668067 = 8668510
449 + 8668061 = 8668510

Showing the first eight; more decompositions exist.
