Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142140, here are decompositions:

17 + 142123 = 142140
29 + 142111 = 142140
41 + 142099 = 142140
43 + 142097 = 142140
73 + 142067 = 142140
79 + 142061 = 142140
83 + 142057 = 142140
101 + 142039 = 142140

Showing the first eight; more decompositions exist.
