Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595294, here are decompositions:

43 + 31595251 = 31595294
193 + 31595101 = 31595294
307 + 31594987 = 31595294
331 + 31594963 = 31595294
421 + 31594873 = 31595294
433 + 31594861 = 31595294
487 + 31594807 = 31595294
547 + 31594747 = 31595294

Showing the first eight; more decompositions exist.
