Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532122, here are decompositions:

5 + 31532117 = 31532122
59 + 31532063 = 31532122
101 + 31532021 = 31532122
191 + 31531931 = 31532122
239 + 31531883 = 31532122
443 + 31531679 = 31532122
599 + 31531523 = 31532122
701 + 31531421 = 31532122

Showing the first eight; more decompositions exist.
