Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179830, here are decompositions:

3 + 179827 = 179830
11 + 179819 = 179830
17 + 179813 = 179830
23 + 179807 = 179830
29 + 179801 = 179830
113 + 179717 = 179830
137 + 179693 = 179830
173 + 179657 = 179830

Showing the first eight; more decompositions exist.
