Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730920, here are decompositions:

7 + 8730913 = 8730920
19 + 8730901 = 8730920
31 + 8730889 = 8730920
61 + 8730859 = 8730920
73 + 8730847 = 8730920
127 + 8730793 = 8730920
139 + 8730781 = 8730920
223 + 8730697 = 8730920

Showing the first eight; more decompositions exist.
