Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712522, here are decompositions:

31 + 8712491 = 8712522
101 + 8712421 = 8712522
149 + 8712373 = 8712522
151 + 8712371 = 8712522
173 + 8712349 = 8712522
199 + 8712323 = 8712522
211 + 8712311 = 8712522
229 + 8712293 = 8712522

Showing the first eight; more decompositions exist.
