Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166802, here are decompositions:

3 + 166799 = 166802
19 + 166783 = 166802
61 + 166741 = 166802
79 + 166723 = 166802
109 + 166693 = 166802
193 + 166609 = 166802
199 + 166603 = 166802
241 + 166561 = 166802

Showing the first eight; more decompositions exist.
