Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730420, here are decompositions:

43 + 8730377 = 8730420
67 + 8730353 = 8730420
71 + 8730349 = 8730420
79 + 8730341 = 8730420
89 + 8730331 = 8730420
109 + 8730311 = 8730420
113 + 8730307 = 8730420
137 + 8730283 = 8730420

Showing the first eight; more decompositions exist.
