Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027900, here are decompositions:

17 + 1027883 = 1027900
47 + 1027853 = 1027900
59 + 1027841 = 1027900
101 + 1027799 = 1027900
113 + 1027787 = 1027900
149 + 1027751 = 1027900
173 + 1027727 = 1027900
197 + 1027703 = 1027900

Showing the first eight; more decompositions exist.
