Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593524, here are decompositions:

7 + 31593517 = 31593524
13 + 31593511 = 31593524
181 + 31593343 = 31593524
211 + 31593313 = 31593524
271 + 31593253 = 31593524
331 + 31593193 = 31593524
541 + 31592983 = 31593524
577 + 31592947 = 31593524

Showing the first eight; more decompositions exist.
