Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740780, here are decompositions:

17 + 8740763 = 8740780
23 + 8740757 = 8740780
53 + 8740727 = 8740780
101 + 8740679 = 8740780
131 + 8740649 = 8740780
137 + 8740643 = 8740780
173 + 8740607 = 8740780
239 + 8740541 = 8740780

Showing the first eight; more decompositions exist.
