Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031808, here are decompositions:

47 + 1031761 = 1031808
67 + 1031741 = 1031808
79 + 1031729 = 1031808
101 + 1031707 = 1031808
131 + 1031677 = 1031808
139 + 1031669 = 1031808
179 + 1031629 = 1031808
199 + 1031609 = 1031808

Showing the first eight; more decompositions exist.
