Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945646, here are decompositions:

17 + 945629 = 945646
59 + 945587 = 945646
167 + 945479 = 945646
173 + 945473 = 945646
257 + 945389 = 945646
269 + 945377 = 945646
353 + 945293 = 945646
419 + 945227 = 945646

Showing the first eight; more decompositions exist.
