Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977872, here are decompositions:

11 + 977861 = 977872
23 + 977849 = 977872
41 + 977831 = 977872
53 + 977819 = 977872
59 + 977813 = 977872
149 + 977723 = 977872
179 + 977693 = 977872
191 + 977681 = 977872

Showing the first eight; more decompositions exist.
