Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182940, here are decompositions:

7 + 182933 = 182940
11 + 182929 = 182940
13 + 182927 = 182940
19 + 182921 = 182940
41 + 182899 = 182940
47 + 182893 = 182940
53 + 182887 = 182940
73 + 182867 = 182940

Showing the first eight; more decompositions exist.
