Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588194, here are decompositions:

23 + 31588171 = 31588194
37 + 31588157 = 31588194
107 + 31588087 = 31588194
191 + 31588003 = 31588194
233 + 31587961 = 31588194
251 + 31587943 = 31588194
271 + 31587923 = 31588194
283 + 31587911 = 31588194

Showing the first eight; more decompositions exist.
