Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42744, here are decompositions:

7 + 42737 = 42744
17 + 42727 = 42744
41 + 42703 = 42744
43 + 42701 = 42744
47 + 42697 = 42744
61 + 42683 = 42744
67 + 42677 = 42744
101 + 42643 = 42744

Showing the first eight; more decompositions exist.
