Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637330, here are decompositions:

7 + 8637323 = 8637330
11 + 8637319 = 8637330
19 + 8637311 = 8637330
29 + 8637301 = 8637330
41 + 8637289 = 8637330
67 + 8637263 = 8637330
73 + 8637257 = 8637330
83 + 8637247 = 8637330

Showing the first eight; more decompositions exist.
