Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712562, here are decompositions:

29 + 8712533 = 8712562
71 + 8712491 = 8712562
191 + 8712371 = 8712562
239 + 8712323 = 8712562
251 + 8712311 = 8712562
269 + 8712293 = 8712562
281 + 8712281 = 8712562
293 + 8712269 = 8712562

Showing the first eight; more decompositions exist.
