Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977530, here are decompositions:

17 + 977513 = 977530
23 + 977507 = 977530
83 + 977447 = 977530
167 + 977363 = 977530
173 + 977357 = 977530
179 + 977351 = 977530
347 + 977183 = 977530
383 + 977147 = 977530

Showing the first eight; more decompositions exist.
