Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532146, here are decompositions:

5 + 31532141 = 31532146
29 + 31532117 = 31532146
83 + 31532063 = 31532146
179 + 31531967 = 31532146
263 + 31531883 = 31532146
419 + 31531727 = 31532146
467 + 31531679 = 31532146
479 + 31531667 = 31532146

Showing the first eight; more decompositions exist.
