Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142230, here are decompositions:

7 + 142223 = 142230
13 + 142217 = 142230
19 + 142211 = 142230
37 + 142193 = 142230
41 + 142189 = 142230
47 + 142183 = 142230
61 + 142169 = 142230
71 + 142159 = 142230

Showing the first eight; more decompositions exist.
