Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22778, here are decompositions:

37 + 22741 = 22778
61 + 22717 = 22778
79 + 22699 = 22778
109 + 22669 = 22778
127 + 22651 = 22778
139 + 22639 = 22778
157 + 22621 = 22778
211 + 22567 = 22778

Showing the first eight; more decompositions exist.
