Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595174, here are decompositions:

73 + 31595101 = 31595174
211 + 31594963 = 31595174
271 + 31594903 = 31595174
307 + 31594867 = 31595174
313 + 31594861 = 31595174
367 + 31594807 = 31595174
547 + 31594627 = 31595174
577 + 31594597 = 31595174

Showing the first eight; more decompositions exist.
