Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638258, here are decompositions:

11 + 8638247 = 8638258
17 + 8638241 = 8638258
29 + 8638229 = 8638258
59 + 8638199 = 8638258
71 + 8638187 = 8638258
107 + 8638151 = 8638258
137 + 8638121 = 8638258
191 + 8638067 = 8638258

Showing the first eight; more decompositions exist.
