Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528824, here are decompositions:

11 + 31528813 = 31528824
13 + 31528811 = 31528824
17 + 31528807 = 31528824
23 + 31528801 = 31528824
73 + 31528751 = 31528824
83 + 31528741 = 31528824
101 + 31528723 = 31528824
127 + 31528697 = 31528824

Showing the first eight; more decompositions exist.
