Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142260, here are decompositions:

23 + 142237 = 142260
29 + 142231 = 142260
37 + 142223 = 142260
43 + 142217 = 142260
67 + 142193 = 142260
71 + 142189 = 142260
101 + 142159 = 142260
103 + 142157 = 142260

Showing the first eight; more decompositions exist.
