Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180676, here are decompositions:

29 + 180647 = 180676
47 + 180629 = 180676
53 + 180623 = 180676
59 + 180617 = 180676
107 + 180569 = 180676
113 + 180563 = 180676
137 + 180539 = 180676
173 + 180503 = 180676

Showing the first eight; more decompositions exist.
