Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180684, here are decompositions:

5 + 180679 = 180684
17 + 180667 = 180684
37 + 180647 = 180684
61 + 180623 = 180684
67 + 180617 = 180684
137 + 180547 = 180684
151 + 180533 = 180684
173 + 180511 = 180684

Showing the first eight; more decompositions exist.
