Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977788, here are decompositions:

41 + 977747 = 977788
107 + 977681 = 977788
179 + 977609 = 977788
197 + 977591 = 977788
281 + 977507 = 977788
419 + 977369 = 977788
431 + 977357 = 977788
641 + 977147 = 977788

Showing the first eight; more decompositions exist.
