Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593020, here are decompositions:

37 + 31592983 = 31593020
61 + 31592959 = 31593020
73 + 31592947 = 31593020
97 + 31592923 = 31593020
211 + 31592809 = 31593020
223 + 31592797 = 31593020
241 + 31592779 = 31593020
337 + 31592683 = 31593020

Showing the first eight; more decompositions exist.
