Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593572, here are decompositions:

19 + 31593553 = 31593572
61 + 31593511 = 31593572
181 + 31593391 = 31593572
229 + 31593343 = 31593572
379 + 31593193 = 31593572
463 + 31593109 = 31593572
541 + 31593031 = 31593572
601 + 31592971 = 31593572

Showing the first eight; more decompositions exist.
