Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992220, here are decompositions:

37 + 992183 = 992220
41 + 992179 = 992220
67 + 992153 = 992220
79 + 992141 = 992220
107 + 992113 = 992220
109 + 992111 = 992220
197 + 992023 = 992220
199 + 992021 = 992220

Showing the first eight; more decompositions exist.
