Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595048, here are decompositions:

61 + 31594987 = 31595048
181 + 31594867 = 31595048
241 + 31594807 = 31595048
349 + 31594699 = 31595048
367 + 31594681 = 31595048
421 + 31594627 = 31595048
439 + 31594609 = 31595048
547 + 31594501 = 31595048

Showing the first eight; more decompositions exist.
