Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532028, here are decompositions:

7 + 31532021 = 31532028
61 + 31531967 = 31532028
97 + 31531931 = 31532028
107 + 31531921 = 31532028
211 + 31531817 = 31532028
277 + 31531751 = 31532028
349 + 31531679 = 31532028
379 + 31531649 = 31532028

Showing the first eight; more decompositions exist.
