Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977986, here are decompositions:

59 + 977927 = 977986
89 + 977897 = 977986
137 + 977849 = 977986
167 + 977819 = 977986
173 + 977813 = 977986
239 + 977747 = 977986
263 + 977723 = 977986
293 + 977693 = 977986

Showing the first eight; more decompositions exist.
