Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77222, here are decompositions:

31 + 77191 = 77222
181 + 77041 = 77222
193 + 77029 = 77222
199 + 77023 = 77222
349 + 76873 = 77222
421 + 76801 = 77222
571 + 76651 = 77222
619 + 76603 = 77222

Showing the first eight; more decompositions exist.
