Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977782, here are decompositions:

59 + 977723 = 977782
89 + 977693 = 977782
101 + 977681 = 977782
173 + 977609 = 977782
191 + 977591 = 977782
269 + 977513 = 977782
419 + 977363 = 977782
431 + 977351 = 977782

Showing the first eight; more decompositions exist.
