Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759142, here are decompositions:

5 + 8759137 = 8759142
19 + 8759123 = 8759142
53 + 8759089 = 8759142
83 + 8759059 = 8759142
103 + 8759039 = 8759142
109 + 8759033 = 8759142
149 + 8758993 = 8759142
163 + 8758979 = 8759142

Showing the first eight; more decompositions exist.
