Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730406, here are decompositions:

29 + 8730377 = 8730406
53 + 8730353 = 8730406
137 + 8730269 = 8730406
149 + 8730257 = 8730406
257 + 8730149 = 8730406
467 + 8729939 = 8730406
557 + 8729849 = 8730406
569 + 8729837 = 8730406

Showing the first eight; more decompositions exist.
