Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740720, here are decompositions:

41 + 8740679 = 8740720
71 + 8740649 = 8740720
113 + 8740607 = 8740720
179 + 8740541 = 8740720
227 + 8740493 = 8740720
293 + 8740427 = 8740720
347 + 8740373 = 8740720
353 + 8740367 = 8740720

Showing the first eight; more decompositions exist.
