Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595002, here are decompositions:

3 + 31594999 = 31595002
11 + 31594991 = 31595002
41 + 31594961 = 31595002
71 + 31594931 = 31595002
83 + 31594919 = 31595002
191 + 31594811 = 31595002
233 + 31594769 = 31595002
311 + 31594691 = 31595002

Showing the first eight; more decompositions exist.
