Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977228, here are decompositions:

19 + 977209 = 977228
37 + 977191 = 977228
61 + 977167 = 977228
79 + 977149 = 977228
181 + 977047 = 977228
271 + 976957 = 977228
277 + 976951 = 977228
379 + 976849 = 977228

Showing the first eight; more decompositions exist.
