Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977660, here are decompositions:

31 + 977629 = 977660
67 + 977593 = 977660
139 + 977521 = 977660
223 + 977437 = 977660
337 + 977323 = 977660
421 + 977239 = 977660
457 + 977203 = 977660
613 + 977047 = 977660

Showing the first eight; more decompositions exist.
