Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945220, here are decompositions:

11 + 945209 = 945220
41 + 945179 = 945220
131 + 945089 = 945220
233 + 944987 = 945220
251 + 944969 = 945220
257 + 944963 = 945220
347 + 944873 = 945220
443 + 944777 = 945220

Showing the first eight; more decompositions exist.
