Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660140, here are decompositions:

53 + 8660087 = 8660140
59 + 8660081 = 8660140
89 + 8660051 = 8660140
101 + 8660039 = 8660140
107 + 8660033 = 8660140
191 + 8659949 = 8660140
227 + 8659913 = 8660140
347 + 8659793 = 8660140

Showing the first eight; more decompositions exist.
