Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179806, here are decompositions:

5 + 179801 = 179806
89 + 179717 = 179806
113 + 179693 = 179806
149 + 179657 = 179806
173 + 179633 = 179806
227 + 179579 = 179806
233 + 179573 = 179806
257 + 179549 = 179806

Showing the first eight; more decompositions exist.
