Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730930, here are decompositions:

11 + 8730919 = 8730930
17 + 8730913 = 8730930
29 + 8730901 = 8730930
37 + 8730893 = 8730930
41 + 8730889 = 8730930
67 + 8730863 = 8730930
71 + 8730859 = 8730930
73 + 8730857 = 8730930

Showing the first eight; more decompositions exist.
