Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992978, here are decompositions:

31 + 992947 = 992978
37 + 992941 = 992978
61 + 992917 = 992978
241 + 992737 = 992978
271 + 992707 = 992978
277 + 992701 = 992978
439 + 992539 = 992978
457 + 992521 = 992978

Showing the first eight; more decompositions exist.
