Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589318, here are decompositions:

31 + 31589287 = 31589318
67 + 31589251 = 31589318
151 + 31589167 = 31589318
181 + 31589137 = 31589318
199 + 31589119 = 31589318
307 + 31589011 = 31589318
367 + 31588951 = 31589318
421 + 31588897 = 31589318

Showing the first eight; more decompositions exist.
