Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729002, here are decompositions:

59 + 8728943 = 8729002
101 + 8728901 = 8729002
179 + 8728823 = 8729002
281 + 8728721 = 8729002
311 + 8728691 = 8729002
353 + 8728649 = 8729002
431 + 8728571 = 8729002
521 + 8728481 = 8729002

Showing the first eight; more decompositions exist.
