Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142268, here are decompositions:

31 + 142237 = 142268
37 + 142231 = 142268
79 + 142189 = 142268
109 + 142159 = 142268
157 + 142111 = 142268
211 + 142057 = 142268
229 + 142039 = 142268
277 + 141991 = 142268

Showing the first eight; more decompositions exist.
