Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588052, here are decompositions:

73 + 31587979 = 31588052
103 + 31587949 = 31588052
109 + 31587943 = 31588052
193 + 31587859 = 31588052
271 + 31587781 = 31588052
619 + 31587433 = 31588052
631 + 31587421 = 31588052
829 + 31587223 = 31588052

Showing the first eight; more decompositions exist.
