Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740990, here are decompositions:

131 + 8740859 = 8740990
149 + 8740841 = 8740990
191 + 8740799 = 8740990
197 + 8740793 = 8740990
227 + 8740763 = 8740990
233 + 8740757 = 8740990
263 + 8740727 = 8740990
311 + 8740679 = 8740990

Showing the first eight; more decompositions exist.
