Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588522, here are decompositions:

29 + 31588493 = 31588522
59 + 31588463 = 31588522
83 + 31588439 = 31588522
191 + 31588331 = 31588522
269 + 31588253 = 31588522
419 + 31588103 = 31588522
461 + 31588061 = 31588522
503 + 31588019 = 31588522

Showing the first eight; more decompositions exist.
