Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730980, here are decompositions:

3 + 8730977 = 8730980
31 + 8730949 = 8730980
61 + 8730919 = 8730980
67 + 8730913 = 8730980
79 + 8730901 = 8730980
199 + 8730781 = 8730980
283 + 8730697 = 8730980
331 + 8730649 = 8730980

Showing the first eight; more decompositions exist.
