Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572596, here are decompositions:

7 + 31572589 = 31572596
37 + 31572559 = 31572596
67 + 31572529 = 31572596
73 + 31572523 = 31572596
193 + 31572403 = 31572596
313 + 31572283 = 31572596
373 + 31572223 = 31572596
439 + 31572157 = 31572596

Showing the first eight; more decompositions exist.
