Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594122, here are decompositions:

41 + 31594081 = 31594122
59 + 31594063 = 31594122
61 + 31594061 = 31594122
73 + 31594049 = 31594122
83 + 31594039 = 31594122
139 + 31593983 = 31594122
163 + 31593959 = 31594122
179 + 31593943 = 31594122

Showing the first eight; more decompositions exist.
