Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724908, here are decompositions:

37 + 8724871 = 8724908
61 + 8724847 = 8724908
109 + 8724799 = 8724908
211 + 8724697 = 8724908
277 + 8724631 = 8724908
307 + 8724601 = 8724908
349 + 8724559 = 8724908
397 + 8724511 = 8724908

Showing the first eight; more decompositions exist.
