Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188826, here are decompositions:

47 + 188779 = 188826
59 + 188767 = 188826
73 + 188753 = 188826
97 + 188729 = 188826
107 + 188719 = 188826
139 + 188687 = 188826
149 + 188677 = 188826
173 + 188653 = 188826

Showing the first eight; more decompositions exist.
