Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730918, here are decompositions:

5 + 8730913 = 8730918
17 + 8730901 = 8730918
29 + 8730889 = 8730918
37 + 8730881 = 8730918
59 + 8730859 = 8730918
61 + 8730857 = 8730918
67 + 8730851 = 8730918
71 + 8730847 = 8730918

Showing the first eight; more decompositions exist.
