Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523052, here are decompositions:

31 + 31523021 = 31523052
73 + 31522979 = 31523052
101 + 31522951 = 31523052
151 + 31522901 = 31523052
163 + 31522889 = 31523052
179 + 31522873 = 31523052
229 + 31522823 = 31523052
359 + 31522693 = 31523052

Showing the first eight; more decompositions exist.
