Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668120, here are decompositions:

47 + 8668073 = 8668120
53 + 8668067 = 8668120
59 + 8668061 = 8668120
89 + 8668031 = 8668120
191 + 8667929 = 8668120
257 + 8667863 = 8668120
311 + 8667809 = 8668120
431 + 8667689 = 8668120

Showing the first eight; more decompositions exist.
