Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595450, here are decompositions:

43 + 31595407 = 31595450
67 + 31595383 = 31595450
79 + 31595371 = 31595450
199 + 31595251 = 31595450
241 + 31595209 = 31595450
277 + 31595173 = 31595450
349 + 31595101 = 31595450
463 + 31594987 = 31595450

Showing the first eight; more decompositions exist.
