Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588030, here are decompositions:

11 + 31588019 = 31588030
107 + 31587923 = 31588030
137 + 31587893 = 31588030
251 + 31587779 = 31588030
263 + 31587767 = 31588030
281 + 31587749 = 31588030
293 + 31587737 = 31588030
443 + 31587587 = 31588030

Showing the first eight; more decompositions exist.
