Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180244, here are decompositions:

3 + 180241 = 180244
5 + 180239 = 180244
11 + 180233 = 180244
23 + 180221 = 180244
83 + 180161 = 180244
107 + 180137 = 180244
167 + 180077 = 180244
173 + 180071 = 180244

Showing the first eight; more decompositions exist.
