Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687502, here are decompositions:

23 + 8687479 = 8687502
41 + 8687461 = 8687502
73 + 8687429 = 8687502
79 + 8687423 = 8687502
101 + 8687401 = 8687502
139 + 8687363 = 8687502
181 + 8687321 = 8687502
193 + 8687309 = 8687502

Showing the first eight; more decompositions exist.
