Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023586, here are decompositions:

29 + 1023557 = 1023586
167 + 1023419 = 1023586
173 + 1023413 = 1023586
197 + 1023389 = 1023586
233 + 1023353 = 1023586
257 + 1023329 = 1023586
269 + 1023317 = 1023586
359 + 1023227 = 1023586

Showing the first eight; more decompositions exist.
