Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180394, here are decompositions:

3 + 180391 = 180394
23 + 180371 = 180394
47 + 180347 = 180394
83 + 180311 = 180394
107 + 180287 = 180394
113 + 180281 = 180394
131 + 180263 = 180394
173 + 180221 = 180394

Showing the first eight; more decompositions exist.
