Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729636, here are decompositions:

7 + 8729629 = 8729636
43 + 8729593 = 8729636
73 + 8729563 = 8729636
79 + 8729557 = 8729636
313 + 8729323 = 8729636
397 + 8729239 = 8729636
457 + 8729179 = 8729636
463 + 8729173 = 8729636

Showing the first eight; more decompositions exist.
