Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027918, here are decompositions:

131 + 1027787 = 1027918
167 + 1027751 = 1027918
179 + 1027739 = 1027918
191 + 1027727 = 1027918
239 + 1027679 = 1027918
431 + 1027487 = 1027918
491 + 1027427 = 1027918
509 + 1027409 = 1027918

Showing the first eight; more decompositions exist.
