Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660370, here are decompositions:

31 + 8660339 = 8660370
73 + 8660297 = 8660370
79 + 8660291 = 8660370
83 + 8660287 = 8660370
101 + 8660269 = 8660370
107 + 8660263 = 8660370
137 + 8660233 = 8660370
149 + 8660221 = 8660370

Showing the first eight; more decompositions exist.
