Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739528, here are decompositions:

29 + 8739499 = 8739528
37 + 8739491 = 8739528
47 + 8739481 = 8739528
97 + 8739431 = 8739528
131 + 8739397 = 8739528
137 + 8739391 = 8739528
139 + 8739389 = 8739528
179 + 8739349 = 8739528

Showing the first eight; more decompositions exist.
