Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712748, here are decompositions:

47 + 8712701 = 8712748
71 + 8712677 = 8712748
137 + 8712611 = 8712748
251 + 8712497 = 8712748
257 + 8712491 = 8712748
461 + 8712287 = 8712748
467 + 8712281 = 8712748
479 + 8712269 = 8712748

Showing the first eight; more decompositions exist.
