Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740778, here are decompositions:

97 + 8740681 = 8740778
199 + 8740579 = 8740778
331 + 8740447 = 8740778
349 + 8740429 = 8740778
367 + 8740411 = 8740778
457 + 8740321 = 8740778
661 + 8740117 = 8740778
691 + 8740087 = 8740778

Showing the first eight; more decompositions exist.
