Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594194, here are decompositions:

31 + 31594163 = 31594194
43 + 31594151 = 31594194
61 + 31594133 = 31594194
97 + 31594097 = 31594194
113 + 31594081 = 31594194
131 + 31594063 = 31594194
211 + 31593983 = 31594194
241 + 31593953 = 31594194

Showing the first eight; more decompositions exist.
