Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179890, here are decompositions:

41 + 179849 = 179890
71 + 179819 = 179890
83 + 179807 = 179890
89 + 179801 = 179890
173 + 179717 = 179890
197 + 179693 = 179890
233 + 179657 = 179890
239 + 179651 = 179890

Showing the first eight; more decompositions exist.
