Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42986, here are decompositions:

7 + 42979 = 42986
19 + 42967 = 42986
43 + 42943 = 42986
127 + 42859 = 42986
157 + 42829 = 42986
193 + 42793 = 42986
199 + 42787 = 42986
277 + 42709 = 42986

Showing the first eight; more decompositions exist.
