Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42724, here are decompositions:

5 + 42719 = 42724
23 + 42701 = 42724
41 + 42683 = 42724
47 + 42677 = 42724
83 + 42641 = 42724
113 + 42611 = 42724
167 + 42557 = 42724
191 + 42533 = 42724

Showing the first eight; more decompositions exist.
