Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637320, here are decompositions:

19 + 8637301 = 8637320
31 + 8637289 = 8637320
67 + 8637253 = 8637320
73 + 8637247 = 8637320
157 + 8637163 = 8637320
229 + 8637091 = 8637320
313 + 8637007 = 8637320
331 + 8636989 = 8637320

Showing the first eight; more decompositions exist.
