Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180370, here are decompositions:

23 + 180347 = 180370
53 + 180317 = 180370
59 + 180311 = 180370
83 + 180287 = 180370
89 + 180281 = 180370
107 + 180263 = 180370
131 + 180239 = 180370
137 + 180233 = 180370

Showing the first eight; more decompositions exist.
