Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614218, here are decompositions:

37 + 8614181 = 8614218
47 + 8614171 = 8614218
59 + 8614159 = 8614218
61 + 8614157 = 8614218
89 + 8614129 = 8614218
101 + 8614117 = 8614218
139 + 8614079 = 8614218
167 + 8614051 = 8614218

Showing the first eight; more decompositions exist.
