Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180738, here are decompositions:

7 + 180731 = 180738
37 + 180701 = 180738
59 + 180679 = 180738
71 + 180667 = 180738
109 + 180629 = 180738
191 + 180547 = 180738
197 + 180541 = 180738
199 + 180539 = 180738

Showing the first eight; more decompositions exist.
