Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188726, here are decompositions:

7 + 188719 = 188726
19 + 188707 = 188726
73 + 188653 = 188726
163 + 188563 = 188726
193 + 188533 = 188726
199 + 188527 = 188726
283 + 188443 = 188726
337 + 188389 = 188726

Showing the first eight; more decompositions exist.
