Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169088, here are decompositions:

19 + 169069 = 169088
79 + 169009 = 169088
97 + 168991 = 169088
151 + 168937 = 169088
307 + 168781 = 169088
457 + 168631 = 169088
487 + 168601 = 169088
547 + 168541 = 169088

Showing the first eight; more decompositions exist.
