Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729044, here are decompositions:

11 + 8729033 = 8729044
101 + 8728943 = 8729044
257 + 8728787 = 8729044
353 + 8728691 = 8729044
563 + 8728481 = 8729044
587 + 8728457 = 8729044
617 + 8728427 = 8729044
647 + 8728397 = 8729044

Showing the first eight; more decompositions exist.
