Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740560, here are decompositions:

19 + 8740541 = 8740560
29 + 8740531 = 8740560
41 + 8740519 = 8740560
43 + 8740517 = 8740560
67 + 8740493 = 8740560
107 + 8740453 = 8740560
113 + 8740447 = 8740560
131 + 8740429 = 8740560

Showing the first eight; more decompositions exist.
