Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532202, here are decompositions:

61 + 31532141 = 31532202
89 + 31532113 = 31532202
113 + 31532089 = 31532202
131 + 31532071 = 31532202
139 + 31532063 = 31532202
181 + 31532021 = 31532202
199 + 31532003 = 31532202
271 + 31531931 = 31532202

Showing the first eight; more decompositions exist.
