Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180552, here are decompositions:

5 + 180547 = 180552
11 + 180541 = 180552
13 + 180539 = 180552
19 + 180533 = 180552
41 + 180511 = 180552
61 + 180491 = 180552
79 + 180473 = 180552
89 + 180463 = 180552

Showing the first eight; more decompositions exist.
