Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588294, here are decompositions:

41 + 31588253 = 31588294
47 + 31588247 = 31588294
137 + 31588157 = 31588294
191 + 31588103 = 31588294
233 + 31588061 = 31588294
383 + 31587911 = 31588294
401 + 31587893 = 31588294
557 + 31587737 = 31588294

Showing the first eight; more decompositions exist.
