Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743648, here are decompositions:

59 + 8743589 = 8743648
101 + 8743547 = 8743648
149 + 8743499 = 8743648
227 + 8743421 = 8743648
239 + 8743409 = 8743648
269 + 8743379 = 8743648
281 + 8743367 = 8743648
317 + 8743331 = 8743648

Showing the first eight; more decompositions exist.
