Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565424, here are decompositions:

13 + 31565411 = 31565424
41 + 31565383 = 31565424
47 + 31565377 = 31565424
71 + 31565353 = 31565424
73 + 31565351 = 31565424
101 + 31565323 = 31565424
127 + 31565297 = 31565424
131 + 31565293 = 31565424

Showing the first eight; more decompositions exist.
