Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594218, here are decompositions:

59 + 31594159 = 31594218
67 + 31594151 = 31594218
137 + 31594081 = 31594218
157 + 31594061 = 31594218
179 + 31594039 = 31594218
281 + 31593937 = 31594218
317 + 31593901 = 31594218
349 + 31593869 = 31594218

Showing the first eight; more decompositions exist.
