Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538896, here are decompositions:

89 + 31538807 = 31538896
107 + 31538789 = 31538896
167 + 31538729 = 31538896
317 + 31538579 = 31538896
419 + 31538477 = 31538896
563 + 31538333 = 31538896
569 + 31538327 = 31538896
743 + 31538153 = 31538896

Showing the first eight; more decompositions exist.
