Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755240, here are decompositions:

23 + 8755217 = 8755240
167 + 8755073 = 8755240
191 + 8755049 = 8755240
239 + 8755001 = 8755240
269 + 8754971 = 8755240
281 + 8754959 = 8755240
467 + 8754773 = 8755240
509 + 8754731 = 8755240

Showing the first eight; more decompositions exist.
