Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593260, here are decompositions:

7 + 31593253 = 31593260
67 + 31593193 = 31593260
151 + 31593109 = 31593260
163 + 31593097 = 31593260
229 + 31593031 = 31593260
277 + 31592983 = 31593260
313 + 31592947 = 31593260
337 + 31592923 = 31593260

Showing the first eight; more decompositions exist.
