Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978788, here are decompositions:

61 + 978727 = 978788
277 + 978511 = 978788
331 + 978457 = 978788
439 + 978349 = 978788
571 + 978217 = 978788
607 + 978181 = 978788
631 + 978157 = 978788
709 + 978079 = 978788

Showing the first eight; more decompositions exist.
