Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027850, here are decompositions:

67 + 1027783 = 1027850
73 + 1027777 = 1027850
97 + 1027753 = 1027850
157 + 1027693 = 1027850
163 + 1027687 = 1027850
283 + 1027567 = 1027850
331 + 1027519 = 1027850
367 + 1027483 = 1027850

Showing the first eight; more decompositions exist.
