Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523884, here are decompositions:

3 + 31523881 = 31523884
83 + 31523801 = 31523884
131 + 31523753 = 31523884
233 + 31523651 = 31523884
251 + 31523633 = 31523884
347 + 31523537 = 31523884
443 + 31523441 = 31523884
503 + 31523381 = 31523884

Showing the first eight; more decompositions exist.
