Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45842, here are decompositions:

19 + 45823 = 45842
79 + 45763 = 45842
151 + 45691 = 45842
211 + 45631 = 45842
229 + 45613 = 45842
409 + 45433 = 45842
439 + 45403 = 45842
499 + 45343 = 45842

Showing the first eight; more decompositions exist.
