Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532184, here are decompositions:

17 + 31532167 = 31532184
43 + 31532141 = 31532184
67 + 31532117 = 31532184
71 + 31532113 = 31532184
113 + 31532071 = 31532184
163 + 31532021 = 31532184
181 + 31532003 = 31532184
263 + 31531921 = 31532184

Showing the first eight; more decompositions exist.
