Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180946, here are decompositions:

149 + 180797 = 180946
167 + 180779 = 180946
173 + 180773 = 180946
197 + 180749 = 180946
317 + 180629 = 180946
383 + 180563 = 180946
443 + 180503 = 180946
449 + 180497 = 180946

Showing the first eight; more decompositions exist.
