Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595120, here are decompositions:

19 + 31595101 = 31595120
61 + 31595059 = 31595120
157 + 31594963 = 31595120
307 + 31594813 = 31595120
313 + 31594807 = 31595120
373 + 31594747 = 31595120
421 + 31594699 = 31595120
439 + 31594681 = 31595120

Showing the first eight; more decompositions exist.
