Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667212, here are decompositions:

61 + 8667151 = 8667212
109 + 8667103 = 8667212
223 + 8666989 = 8667212
331 + 8666881 = 8667212
349 + 8666863 = 8667212
373 + 8666839 = 8667212
439 + 8666773 = 8667212
733 + 8666479 = 8667212

Showing the first eight; more decompositions exist.
