Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588600, here are decompositions:

107 + 31588493 = 31588600
137 + 31588463 = 31588600
233 + 31588367 = 31588600
269 + 31588331 = 31588600
293 + 31588307 = 31588600
347 + 31588253 = 31588600
353 + 31588247 = 31588600
401 + 31588199 = 31588600

Showing the first eight; more decompositions exist.
