Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528052, here are decompositions:

139 + 31527913 = 31528052
223 + 31527829 = 31528052
271 + 31527781 = 31528052
349 + 31527703 = 31528052
571 + 31527481 = 31528052
709 + 31527343 = 31528052
859 + 31527193 = 31528052
1153 + 31526899 = 31528052

Showing the first eight; more decompositions exist.
