Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687374, here are decompositions:

5 + 8687369 = 8687374
11 + 8687363 = 8687374
53 + 8687321 = 8687374
71 + 8687303 = 8687374
83 + 8687291 = 8687374
167 + 8687207 = 8687374
191 + 8687183 = 8687374
233 + 8687141 = 8687374

Showing the first eight; more decompositions exist.
