Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687912, here are decompositions:

31 + 8687881 = 8687912
199 + 8687713 = 8687912
241 + 8687671 = 8687912
271 + 8687641 = 8687912
313 + 8687599 = 8687912
433 + 8687479 = 8687912
613 + 8687299 = 8687912
823 + 8687089 = 8687912

Showing the first eight; more decompositions exist.
