Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42750, here are decompositions:

7 + 42743 = 42750
13 + 42737 = 42750
23 + 42727 = 42750
31 + 42719 = 42750
41 + 42709 = 42750
47 + 42703 = 42750
53 + 42697 = 42750
61 + 42689 = 42750

Showing the first eight; more decompositions exist.
