Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650942, here are decompositions:

23 + 8650919 = 8650942
149 + 8650793 = 8650942
233 + 8650709 = 8650942
239 + 8650703 = 8650942
269 + 8650673 = 8650942
359 + 8650583 = 8650942
383 + 8650559 = 8650942
401 + 8650541 = 8650942

Showing the first eight; more decompositions exist.
