Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532950, here are decompositions:

11 + 31532939 = 31532950
83 + 31532867 = 31532950
173 + 31532777 = 31532950
257 + 31532693 = 31532950
263 + 31532687 = 31532950
311 + 31532639 = 31532950
353 + 31532597 = 31532950
443 + 31532507 = 31532950

Showing the first eight; more decompositions exist.
