Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739728, here are decompositions:

7 + 8739721 = 8739728
61 + 8739667 = 8739728
199 + 8739529 = 8739728
229 + 8739499 = 8739728
331 + 8739397 = 8739728
337 + 8739391 = 8739728
379 + 8739349 = 8739728
397 + 8739331 = 8739728

Showing the first eight; more decompositions exist.
