Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505596, here are decompositions:

29 + 31505567 = 31505596
107 + 31505489 = 31505596
137 + 31505459 = 31505596
149 + 31505447 = 31505596
263 + 31505333 = 31505596
293 + 31505303 = 31505596
383 + 31505213 = 31505596
557 + 31505039 = 31505596

Showing the first eight; more decompositions exist.
