Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183722, here are decompositions:

13 + 183709 = 183722
31 + 183691 = 183722
61 + 183661 = 183722
151 + 183571 = 183722
199 + 183523 = 183722
211 + 183511 = 183722
223 + 183499 = 183722
271 + 183451 = 183722

Showing the first eight; more decompositions exist.
