Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730942, here are decompositions:

13 + 8730929 = 8730942
23 + 8730919 = 8730942
29 + 8730913 = 8730942
41 + 8730901 = 8730942
53 + 8730889 = 8730942
61 + 8730881 = 8730942
79 + 8730863 = 8730942
83 + 8730859 = 8730942

Showing the first eight; more decompositions exist.
