Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743740, here are decompositions:

7 + 8743733 = 8743740
23 + 8743717 = 8743740
29 + 8743711 = 8743740
59 + 8743681 = 8743740
67 + 8743673 = 8743740
101 + 8743639 = 8743740
107 + 8743633 = 8743740
151 + 8743589 = 8743740

Showing the first eight; more decompositions exist.
