Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40146, here are decompositions:

17 + 40129 = 40146
19 + 40127 = 40146
23 + 40123 = 40146
47 + 40099 = 40146
53 + 40093 = 40146
59 + 40087 = 40146
83 + 40063 = 40146
107 + 40039 = 40146

Showing the first eight; more decompositions exist.
