Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22770, here are decompositions:

19 + 22751 = 22770
29 + 22741 = 22770
31 + 22739 = 22770
43 + 22727 = 22770
53 + 22717 = 22770
61 + 22709 = 22770
71 + 22699 = 22770
73 + 22697 = 22770

Showing the first eight; more decompositions exist.
