Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667210, here are decompositions:

31 + 8667179 = 8667210
43 + 8667167 = 8667210
59 + 8667151 = 8667210
73 + 8667137 = 8667210
89 + 8667121 = 8667210
107 + 8667103 = 8667210
131 + 8667079 = 8667210
257 + 8666953 = 8667210

Showing the first eight; more decompositions exist.
