Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 62440, here are decompositions:

17 + 62423 = 62440
23 + 62417 = 62440
89 + 62351 = 62440
113 + 62327 = 62440
137 + 62303 = 62440
167 + 62273 = 62440
227 + 62213 = 62440
233 + 62207 = 62440

Showing the first eight; more decompositions exist.
