Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596140, here are decompositions:

13 + 31596127 = 31596140
19 + 31596121 = 31596140
73 + 31596067 = 31596140
151 + 31595989 = 31596140
157 + 31595983 = 31596140
211 + 31595929 = 31596140
271 + 31595869 = 31596140
307 + 31595833 = 31596140

Showing the first eight; more decompositions exist.
