Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593266, here are decompositions:

13 + 31593253 = 31593266
73 + 31593193 = 31593266
157 + 31593109 = 31593266
283 + 31592983 = 31593266
307 + 31592959 = 31593266
433 + 31592833 = 31593266
457 + 31592809 = 31593266
487 + 31592779 = 31593266

Showing the first eight; more decompositions exist.
