Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687382, here are decompositions:

13 + 8687369 = 8687382
19 + 8687363 = 8687382
23 + 8687359 = 8687382
61 + 8687321 = 8687382
73 + 8687309 = 8687382
79 + 8687303 = 8687382
83 + 8687299 = 8687382
149 + 8687233 = 8687382

Showing the first eight; more decompositions exist.
