Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168802, here are decompositions:

41 + 168761 = 168802
59 + 168743 = 168802
71 + 168731 = 168802
83 + 168719 = 168802
89 + 168713 = 168802
173 + 168629 = 168802
269 + 168533 = 168802
311 + 168491 = 168802

Showing the first eight; more decompositions exist.
