Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597762, here are decompositions:

23 + 31597739 = 31597762
41 + 31597721 = 31597762
89 + 31597673 = 31597762
149 + 31597613 = 31597762
191 + 31597571 = 31597762
269 + 31597493 = 31597762
479 + 31597283 = 31597762
509 + 31597253 = 31597762

Showing the first eight; more decompositions exist.
