Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660142, here are decompositions:

61 + 8660081 = 8660142
89 + 8660053 = 8660142
103 + 8660039 = 8660142
109 + 8660033 = 8660142
193 + 8659949 = 8660142
229 + 8659913 = 8660142
233 + 8659909 = 8660142
269 + 8659873 = 8660142

Showing the first eight; more decompositions exist.
