Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730906, here are decompositions:

5 + 8730901 = 8730906
13 + 8730893 = 8730906
17 + 8730889 = 8730906
43 + 8730863 = 8730906
47 + 8730859 = 8730906
59 + 8730847 = 8730906
103 + 8730803 = 8730906
109 + 8730797 = 8730906

Showing the first eight; more decompositions exist.
