Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532142, here are decompositions:

29 + 31532113 = 31532142
53 + 31532089 = 31532142
71 + 31532071 = 31532142
79 + 31532063 = 31532142
139 + 31532003 = 31532142
211 + 31531931 = 31532142
233 + 31531909 = 31532142
463 + 31531679 = 31532142

Showing the first eight; more decompositions exist.
