Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730408, here are decompositions:

31 + 8730377 = 8730408
59 + 8730349 = 8730408
67 + 8730341 = 8730408
97 + 8730311 = 8730408
101 + 8730307 = 8730408
139 + 8730269 = 8730408
151 + 8730257 = 8730408
179 + 8730229 = 8730408

Showing the first eight; more decompositions exist.
