Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593530, here are decompositions:

13 + 31593517 = 31593530
19 + 31593511 = 31593530
139 + 31593391 = 31593530
223 + 31593307 = 31593530
277 + 31593253 = 31593530
337 + 31593193 = 31593530
421 + 31593109 = 31593530
433 + 31593097 = 31593530

Showing the first eight; more decompositions exist.
