Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532214, here are decompositions:

5 + 31532209 = 31532214
11 + 31532203 = 31532214
47 + 31532167 = 31532214
73 + 31532141 = 31532214
97 + 31532117 = 31532214
101 + 31532113 = 31532214
151 + 31532063 = 31532214
193 + 31532021 = 31532214

Showing the first eight; more decompositions exist.
