Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182442, here are decompositions:

11 + 182431 = 182442
19 + 182423 = 182442
53 + 182389 = 182442
89 + 182353 = 182442
101 + 182341 = 182442
103 + 182339 = 182442
109 + 182333 = 182442
163 + 182279 = 182442

Showing the first eight; more decompositions exist.
