Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687404, here are decompositions:

3 + 8687401 = 8687404
17 + 8687387 = 8687404
23 + 8687381 = 8687404
41 + 8687363 = 8687404
83 + 8687321 = 8687404
101 + 8687303 = 8687404
113 + 8687291 = 8687404
191 + 8687213 = 8687404

Showing the first eight; more decompositions exist.
