Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42946, here are decompositions:

3 + 42943 = 42946
17 + 42929 = 42946
23 + 42923 = 42946
47 + 42899 = 42946
83 + 42863 = 42946
107 + 42839 = 42946
149 + 42797 = 42946
173 + 42773 = 42946

Showing the first eight; more decompositions exist.
