Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729912, here are decompositions:

31 + 8729881 = 8729912
43 + 8729869 = 8729912
73 + 8729839 = 8729912
223 + 8729689 = 8729912
271 + 8729641 = 8729912
283 + 8729629 = 8729912
349 + 8729563 = 8729912
421 + 8729491 = 8729912

Showing the first eight; more decompositions exist.
