Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678212, here are decompositions:

71 + 8678141 = 8678212
83 + 8678129 = 8678212
131 + 8678081 = 8678212
149 + 8678063 = 8678212
173 + 8678039 = 8678212
233 + 8677979 = 8678212
251 + 8677961 = 8678212
383 + 8677829 = 8678212

Showing the first eight; more decompositions exist.
