Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42976, here are decompositions:

23 + 42953 = 42976
47 + 42929 = 42976
53 + 42923 = 42976
113 + 42863 = 42976
137 + 42839 = 42976
179 + 42797 = 42976
233 + 42743 = 42976
239 + 42737 = 42976

Showing the first eight; more decompositions exist.
