Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189802, here are decompositions:

3 + 189799 = 189802
5 + 189797 = 189802
59 + 189743 = 189802
89 + 189713 = 189802
101 + 189701 = 189802
131 + 189671 = 189802
149 + 189653 = 189802
293 + 189509 = 189802

Showing the first eight; more decompositions exist.
