Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942220, here are decompositions:

3 + 942217 = 942220
53 + 942167 = 942220
107 + 942113 = 942220
179 + 942041 = 942220
239 + 941981 = 942220
317 + 941903 = 942220
359 + 941861 = 942220
449 + 941771 = 942220

Showing the first eight; more decompositions exist.
