Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740678, here are decompositions:

29 + 8740649 = 8740678
71 + 8740607 = 8740678
101 + 8740577 = 8740678
137 + 8740541 = 8740678
251 + 8740427 = 8740678
311 + 8740367 = 8740678
347 + 8740331 = 8740678
389 + 8740289 = 8740678

Showing the first eight; more decompositions exist.
