Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180974, here are decompositions:

67 + 180907 = 180974
103 + 180871 = 180974
127 + 180847 = 180974
163 + 180811 = 180974
181 + 180793 = 180974
223 + 180751 = 180974
307 + 180667 = 180974
433 + 180541 = 180974

Showing the first eight; more decompositions exist.
