Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712612, here are decompositions:

11 + 8712601 = 8712612
79 + 8712533 = 8712612
89 + 8712523 = 8712612
191 + 8712421 = 8712612
239 + 8712373 = 8712612
241 + 8712371 = 8712612
263 + 8712349 = 8712612
331 + 8712281 = 8712612

Showing the first eight; more decompositions exist.
