Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961420, here are decompositions:

23 + 961397 = 961420
101 + 961319 = 961420
107 + 961313 = 961420
137 + 961283 = 961420
179 + 961241 = 961420
233 + 961187 = 961420
263 + 961157 = 961420
269 + 961151 = 961420

Showing the first eight; more decompositions exist.
