Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687984, here are decompositions:

3 + 8687981 = 8687984
31 + 8687953 = 8687984
61 + 8687923 = 8687984
73 + 8687911 = 8687984
103 + 8687881 = 8687984
157 + 8687827 = 8687984
271 + 8687713 = 8687984
313 + 8687671 = 8687984

Showing the first eight; more decompositions exist.
