Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961390, here are decompositions:

71 + 961319 = 961390
107 + 961283 = 961390
113 + 961277 = 961390
149 + 961241 = 961390
233 + 961157 = 961390
239 + 961151 = 961390
251 + 961139 = 961390
257 + 961133 = 961390

Showing the first eight; more decompositions exist.
