Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593974, here are decompositions:

31 + 31593943 = 31593974
37 + 31593937 = 31593974
43 + 31593931 = 31593974
73 + 31593901 = 31593974
211 + 31593763 = 31593974
271 + 31593703 = 31593974
331 + 31593643 = 31593974
367 + 31593607 = 31593974

Showing the first eight; more decompositions exist.
