Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589594, here are decompositions:

193 + 31589401 = 31589594
241 + 31589353 = 31589594
277 + 31589317 = 31589594
307 + 31589287 = 31589594
397 + 31589197 = 31589594
457 + 31589137 = 31589594
577 + 31589017 = 31589594
601 + 31588993 = 31589594

Showing the first eight; more decompositions exist.
