Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180942, here are decompositions:

59 + 180883 = 180942
71 + 180871 = 180942
131 + 180811 = 180942
149 + 180793 = 180942
163 + 180779 = 180942
191 + 180751 = 180942
193 + 180749 = 180942
211 + 180731 = 180942

Showing the first eight; more decompositions exist.
