Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687590, here are decompositions:

3 + 8687587 = 8687590
113 + 8687477 = 8687590
137 + 8687453 = 8687590
167 + 8687423 = 8687590
227 + 8687363 = 8687590
269 + 8687321 = 8687590
281 + 8687309 = 8687590
383 + 8687207 = 8687590

Showing the first eight; more decompositions exist.
