Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730078, here are decompositions:

11 + 8730067 = 8730078
29 + 8730049 = 8730078
79 + 8729999 = 8730078
101 + 8729977 = 8730078
139 + 8729939 = 8730078
191 + 8729887 = 8730078
197 + 8729881 = 8730078
211 + 8729867 = 8730078

Showing the first eight; more decompositions exist.
