Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595000, here are decompositions:

13 + 31594987 = 31595000
37 + 31594963 = 31595000
97 + 31594903 = 31595000
127 + 31594873 = 31595000
139 + 31594861 = 31595000
193 + 31594807 = 31595000
271 + 31594729 = 31595000
373 + 31594627 = 31595000

Showing the first eight; more decompositions exist.
