Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740788, here are decompositions:

5 + 8740783 = 8740788
31 + 8740757 = 8740788
61 + 8740727 = 8740788
107 + 8740681 = 8740788
109 + 8740679 = 8740788
131 + 8740657 = 8740788
139 + 8740649 = 8740788
181 + 8740607 = 8740788

Showing the first eight; more decompositions exist.
