Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977440, here are decompositions:

3 + 977437 = 977440
29 + 977411 = 977440
71 + 977369 = 977440
83 + 977357 = 977440
89 + 977351 = 977440
197 + 977243 = 977440
257 + 977183 = 977440
293 + 977147 = 977440

Showing the first eight; more decompositions exist.
