Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596194, here are decompositions:

31 + 31596163 = 31596194
43 + 31596151 = 31596194
67 + 31596127 = 31596194
73 + 31596121 = 31596194
127 + 31596067 = 31596194
211 + 31595983 = 31596194
313 + 31595881 = 31596194
463 + 31595731 = 31596194

Showing the first eight; more decompositions exist.
