Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640476, here are decompositions:

37 + 8640439 = 8640476
67 + 8640409 = 8640476
127 + 8640349 = 8640476
139 + 8640337 = 8640476
307 + 8640169 = 8640476
367 + 8640109 = 8640476
463 + 8640013 = 8640476
499 + 8639977 = 8640476

Showing the first eight; more decompositions exist.
