Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579596, here are decompositions:

29 + 31579567 = 31579596
53 + 31579543 = 31579596
127 + 31579469 = 31579596
149 + 31579447 = 31579596
197 + 31579399 = 31579596
239 + 31579357 = 31579596
359 + 31579237 = 31579596
383 + 31579213 = 31579596

Showing the first eight; more decompositions exist.
