Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179842, here are decompositions:

23 + 179819 = 179842
29 + 179813 = 179842
41 + 179801 = 179842
149 + 179693 = 179842
191 + 179651 = 179842
239 + 179603 = 179842
251 + 179591 = 179842
263 + 179579 = 179842

Showing the first eight; more decompositions exist.
