Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189826, here are decompositions:

3 + 189823 = 189826
29 + 189797 = 189826
59 + 189767 = 189826
83 + 189743 = 189826
113 + 189713 = 189826
173 + 189653 = 189826
227 + 189599 = 189826
233 + 189593 = 189826

Showing the first eight; more decompositions exist.
