Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730998, here are decompositions:

79 + 8730919 = 8730998
97 + 8730901 = 8730998
109 + 8730889 = 8730998
139 + 8730859 = 8730998
151 + 8730847 = 8730998
307 + 8730691 = 8730998
337 + 8730661 = 8730998
349 + 8730649 = 8730998

Showing the first eight; more decompositions exist.
