Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493596, here are decompositions:

3 + 31493593 = 31493596
23 + 31493573 = 31493596
83 + 31493513 = 31493596
149 + 31493447 = 31493596
257 + 31493339 = 31493596
347 + 31493249 = 31493596
443 + 31493153 = 31493596
557 + 31493039 = 31493596

Showing the first eight; more decompositions exist.
