Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179818, here are decompositions:

5 + 179813 = 179818
11 + 179807 = 179818
17 + 179801 = 179818
101 + 179717 = 179818
131 + 179687 = 179818
167 + 179651 = 179818
227 + 179591 = 179818
239 + 179579 = 179818

Showing the first eight; more decompositions exist.
