Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660422, here are decompositions:

3 + 8660419 = 8660422
41 + 8660381 = 8660422
53 + 8660369 = 8660422
83 + 8660339 = 8660422
131 + 8660291 = 8660422
233 + 8660189 = 8660422
383 + 8660039 = 8660422
389 + 8660033 = 8660422

Showing the first eight; more decompositions exist.
