Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730940, here are decompositions:

11 + 8730929 = 8730940
47 + 8730893 = 8730940
59 + 8730881 = 8730940
83 + 8730857 = 8730940
89 + 8730851 = 8730940
137 + 8730803 = 8730940
311 + 8730629 = 8730940
467 + 8730473 = 8730940

Showing the first eight; more decompositions exist.
