Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122440, here are decompositions:

41 + 122399 = 122440
47 + 122393 = 122440
53 + 122387 = 122440
113 + 122327 = 122440
167 + 122273 = 122440
173 + 122267 = 122440
233 + 122207 = 122440
239 + 122201 = 122440

Showing the first eight; more decompositions exist.
