Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593908, here are decompositions:

7 + 31593901 = 31593908
277 + 31593631 = 31593908
337 + 31593571 = 31593908
397 + 31593511 = 31593908
601 + 31593307 = 31593908
811 + 31593097 = 31593908
877 + 31593031 = 31593908
937 + 31592971 = 31593908

Showing the first eight; more decompositions exist.
