Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739558, here are decompositions:

29 + 8739529 = 8739558
59 + 8739499 = 8739558
67 + 8739491 = 8739558
127 + 8739431 = 8739558
167 + 8739391 = 8739558
199 + 8739359 = 8739558
227 + 8739331 = 8739558
277 + 8739281 = 8739558

Showing the first eight; more decompositions exist.
