Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730208, here are decompositions:

59 + 8730149 = 8730208
131 + 8730077 = 8730208
269 + 8729939 = 8730208
359 + 8729849 = 8730208
479 + 8729729 = 8730208
491 + 8729717 = 8730208
587 + 8729621 = 8730208
797 + 8729411 = 8730208

Showing the first eight; more decompositions exist.
