Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712624, here are decompositions:

13 + 8712611 = 8712624
23 + 8712601 = 8712624
47 + 8712577 = 8712624
101 + 8712523 = 8712624
127 + 8712497 = 8712624
227 + 8712397 = 8712624
251 + 8712373 = 8712624
257 + 8712367 = 8712624

Showing the first eight; more decompositions exist.
