Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730858, here are decompositions:

7 + 8730851 = 8730858
11 + 8730847 = 8730858
61 + 8730797 = 8730858
167 + 8730691 = 8730858
197 + 8730661 = 8730858
229 + 8730629 = 8730858
239 + 8730619 = 8730858
251 + 8730607 = 8730858

Showing the first eight; more decompositions exist.
