Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729942, here are decompositions:

3 + 8729939 = 8729942
19 + 8729923 = 8729942
61 + 8729881 = 8729942
73 + 8729869 = 8729942
103 + 8729839 = 8729942
283 + 8729659 = 8729942
313 + 8729629 = 8729942
349 + 8729593 = 8729942

Showing the first eight; more decompositions exist.
