Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180582, here are decompositions:

13 + 180569 = 180582
19 + 180563 = 180582
41 + 180541 = 180582
43 + 180539 = 180582
71 + 180511 = 180582
79 + 180503 = 180582
109 + 180473 = 180582
163 + 180419 = 180582

Showing the first eight; more decompositions exist.
