Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180546, here are decompositions:

5 + 180541 = 180546
7 + 180539 = 180546
13 + 180533 = 180546
43 + 180503 = 180546
73 + 180473 = 180546
83 + 180463 = 180546
109 + 180437 = 180546
127 + 180419 = 180546

Showing the first eight; more decompositions exist.
