Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730878, here are decompositions:

19 + 8730859 = 8730878
31 + 8730847 = 8730878
97 + 8730781 = 8730878
181 + 8730697 = 8730878
229 + 8730649 = 8730878
271 + 8730607 = 8730878
349 + 8730529 = 8730878
367 + 8730511 = 8730878

Showing the first eight; more decompositions exist.
