Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142248, here are decompositions:

11 + 142237 = 142248
17 + 142231 = 142248
31 + 142217 = 142248
37 + 142211 = 142248
59 + 142189 = 142248
79 + 142169 = 142248
89 + 142159 = 142248
97 + 142151 = 142248

Showing the first eight; more decompositions exist.
