Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739474, here are decompositions:

11 + 8739463 = 8739474
41 + 8739433 = 8739474
43 + 8739431 = 8739474
83 + 8739391 = 8739474
137 + 8739337 = 8739474
193 + 8739281 = 8739474
277 + 8739197 = 8739474
281 + 8739193 = 8739474

Showing the first eight; more decompositions exist.
