Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42340, here are decompositions:

3 + 42337 = 42340
17 + 42323 = 42340
41 + 42299 = 42340
47 + 42293 = 42340
59 + 42281 = 42340
83 + 42257 = 42340
101 + 42239 = 42340
113 + 42227 = 42340

Showing the first eight; more decompositions exist.
