Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729802, here are decompositions:

73 + 8729729 = 8729802
113 + 8729689 = 8729802
173 + 8729629 = 8729802
181 + 8729621 = 8729802
199 + 8729603 = 8729802
239 + 8729563 = 8729802
311 + 8729491 = 8729802
373 + 8729429 = 8729802

Showing the first eight; more decompositions exist.
