Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180774, here are decompositions:

23 + 180751 = 180774
43 + 180731 = 180774
73 + 180701 = 180774
107 + 180667 = 180774
127 + 180647 = 180774
151 + 180623 = 180774
157 + 180617 = 180774
211 + 180563 = 180774

Showing the first eight; more decompositions exist.
