Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42282, here are decompositions:

43 + 42239 = 42282
59 + 42223 = 42282
61 + 42221 = 42282
73 + 42209 = 42282
89 + 42193 = 42282
101 + 42181 = 42282
103 + 42179 = 42282
113 + 42169 = 42282

Showing the first eight; more decompositions exist.
