Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712540, here are decompositions:

7 + 8712533 = 8712540
17 + 8712523 = 8712540
43 + 8712497 = 8712540
167 + 8712373 = 8712540
173 + 8712367 = 8712540
191 + 8712349 = 8712540
229 + 8712311 = 8712540
233 + 8712307 = 8712540

Showing the first eight; more decompositions exist.
