Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572896, here are decompositions:

73 + 31572823 = 31572896
127 + 31572769 = 31572896
163 + 31572733 = 31572896
307 + 31572589 = 31572896
337 + 31572559 = 31572896
367 + 31572529 = 31572896
373 + 31572523 = 31572896
613 + 31572283 = 31572896

Showing the first eight; more decompositions exist.
