Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028086, here are decompositions:

5 + 1028081 = 1028086
23 + 1028063 = 1028086
83 + 1028003 = 1028086
233 + 1027853 = 1028086
347 + 1027739 = 1028086
359 + 1027727 = 1028086
383 + 1027703 = 1028086
443 + 1027643 = 1028086

Showing the first eight; more decompositions exist.
