Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977830, here are decompositions:

11 + 977819 = 977830
17 + 977813 = 977830
83 + 977747 = 977830
107 + 977723 = 977830
137 + 977693 = 977830
149 + 977681 = 977830
239 + 977591 = 977830
263 + 977567 = 977830

Showing the first eight; more decompositions exist.
