Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637384, here are decompositions:

5 + 8637379 = 8637384
11 + 8637373 = 8637384
43 + 8637341 = 8637384
47 + 8637337 = 8637384
61 + 8637323 = 8637384
73 + 8637311 = 8637384
83 + 8637301 = 8637384
127 + 8637257 = 8637384

Showing the first eight; more decompositions exist.
