Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729570, here are decompositions:

7 + 8729563 = 8729570
13 + 8729557 = 8729570
79 + 8729491 = 8729570
103 + 8729467 = 8729570
181 + 8729389 = 8729570
331 + 8729239 = 8729570
349 + 8729221 = 8729570
379 + 8729191 = 8729570

Showing the first eight; more decompositions exist.
