Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730990, here are decompositions:

7 + 8730983 = 8730990
13 + 8730977 = 8730990
41 + 8730949 = 8730990
43 + 8730947 = 8730990
61 + 8730929 = 8730990
71 + 8730919 = 8730990
89 + 8730901 = 8730990
97 + 8730893 = 8730990

Showing the first eight; more decompositions exist.
