Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668454, here are decompositions:

31 + 8668423 = 8668454
73 + 8668381 = 8668454
97 + 8668357 = 8668454
181 + 8668273 = 8668454
313 + 8668141 = 8668454
373 + 8668081 = 8668454
397 + 8668057 = 8668454
523 + 8667931 = 8668454

Showing the first eight; more decompositions exist.
