Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180340, here are decompositions:

3 + 180337 = 180340
23 + 180317 = 180340
29 + 180311 = 180340
53 + 180287 = 180340
59 + 180281 = 180340
101 + 180239 = 180340
107 + 180233 = 180340
179 + 180161 = 180340

Showing the first eight; more decompositions exist.
