Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188788, here are decompositions:

59 + 188729 = 188788
101 + 188687 = 188788
107 + 188681 = 188788
167 + 188621 = 188788
179 + 188609 = 188788
269 + 188519 = 188788
419 + 188369 = 188788
599 + 188189 = 188788

Showing the first eight; more decompositions exist.
