Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687464, here are decompositions:

3 + 8687461 = 8687464
11 + 8687453 = 8687464
41 + 8687423 = 8687464
83 + 8687381 = 8687464
101 + 8687363 = 8687464
173 + 8687291 = 8687464
251 + 8687213 = 8687464
257 + 8687207 = 8687464

Showing the first eight; more decompositions exist.
