Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182436, here are decompositions:

5 + 182431 = 182436
13 + 182423 = 182436
19 + 182417 = 182436
47 + 182389 = 182436
83 + 182353 = 182436
97 + 182339 = 182436
103 + 182333 = 182436
127 + 182309 = 182436

Showing the first eight; more decompositions exist.
