Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698390, here are decompositions:

47 + 8698343 = 8698390
137 + 8698253 = 8698390
149 + 8698241 = 8698390
167 + 8698223 = 8698390
257 + 8698133 = 8698390
269 + 8698121 = 8698390
293 + 8698097 = 8698390
353 + 8698037 = 8698390

Showing the first eight; more decompositions exist.
