Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687546, here are decompositions:

67 + 8687479 = 8687546
79 + 8687467 = 8687546
163 + 8687383 = 8687546
229 + 8687317 = 8687546
313 + 8687233 = 8687546
337 + 8687209 = 8687546
349 + 8687197 = 8687546
397 + 8687149 = 8687546

Showing the first eight; more decompositions exist.
