Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77822, here are decompositions:

61 + 77761 = 77822
79 + 77743 = 77822
103 + 77719 = 77822
109 + 77713 = 77822
163 + 77659 = 77822
181 + 77641 = 77822
211 + 77611 = 77822
271 + 77551 = 77822

Showing the first eight; more decompositions exist.
