Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729408, here are decompositions:

7 + 8729401 = 8729408
19 + 8729389 = 8729408
229 + 8729179 = 8729408
277 + 8729131 = 8729408
349 + 8729059 = 8729408
421 + 8728987 = 8729408
439 + 8728969 = 8729408
487 + 8728921 = 8729408

Showing the first eight; more decompositions exist.
