Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108512, here are decompositions:

13 + 108499 = 108512
73 + 108439 = 108512
211 + 108301 = 108512
223 + 108289 = 108512
241 + 108271 = 108512
373 + 108139 = 108512
433 + 108079 = 108512
499 + 108013 = 108512

Showing the first eight; more decompositions exist.
