Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180544, here are decompositions:

3 + 180541 = 180544
5 + 180539 = 180544
11 + 180533 = 180544
41 + 180503 = 180544
47 + 180497 = 180544
53 + 180491 = 180544
71 + 180473 = 180544
107 + 180437 = 180544

Showing the first eight; more decompositions exist.
