Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10426, here are decompositions:

83 + 10343 = 10426
89 + 10337 = 10426
113 + 10313 = 10426
137 + 10289 = 10426
167 + 10259 = 10426
173 + 10253 = 10426
179 + 10247 = 10426
233 + 10193 = 10426

Showing the first eight; more decompositions exist.
