Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612218, here are decompositions:

179 + 8612039 = 8612218
227 + 8611991 = 8612218
257 + 8611961 = 8612218
359 + 8611859 = 8612218
389 + 8611829 = 8612218
509 + 8611709 = 8612218
521 + 8611697 = 8612218
599 + 8611619 = 8612218

Showing the first eight; more decompositions exist.
