Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42046, here are decompositions:

3 + 42043 = 42046
23 + 42023 = 42046
29 + 42017 = 42046
47 + 41999 = 42046
89 + 41957 = 42046
149 + 41897 = 42046
167 + 41879 = 42046
197 + 41849 = 42046

Showing the first eight; more decompositions exist.
