Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977978, here are decompositions:

7 + 977971 = 977978
97 + 977881 = 977978
307 + 977671 = 977978
349 + 977629 = 977978
367 + 977611 = 977978
439 + 977539 = 977978
457 + 977521 = 977978
541 + 977437 = 977978

Showing the first eight; more decompositions exist.
