Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532196, here are decompositions:

29 + 31532167 = 31532196
79 + 31532117 = 31532196
83 + 31532113 = 31532196
107 + 31532089 = 31532196
193 + 31532003 = 31532196
229 + 31531967 = 31532196
313 + 31531883 = 31532196
379 + 31531817 = 31532196

Showing the first eight; more decompositions exist.
