Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712582, here are decompositions:

5 + 8712577 = 8712582
59 + 8712523 = 8712582
211 + 8712371 = 8712582
233 + 8712349 = 8712582
271 + 8712311 = 8712582
313 + 8712269 = 8712582
349 + 8712233 = 8712582
353 + 8712229 = 8712582

Showing the first eight; more decompositions exist.
