Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42726, here are decompositions:

7 + 42719 = 42726
17 + 42709 = 42726
23 + 42703 = 42726
29 + 42697 = 42726
37 + 42689 = 42726
43 + 42683 = 42726
59 + 42667 = 42726
83 + 42643 = 42726

Showing the first eight; more decompositions exist.
