Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589552, here are decompositions:

13 + 31589539 = 31589552
79 + 31589473 = 31589552
151 + 31589401 = 31589552
193 + 31589359 = 31589552
199 + 31589353 = 31589552
223 + 31589329 = 31589552
433 + 31589119 = 31589552
541 + 31589011 = 31589552

Showing the first eight; more decompositions exist.
