Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593906, here are decompositions:

5 + 31593901 = 31593906
37 + 31593869 = 31593906
67 + 31593839 = 31593906
73 + 31593833 = 31593906
109 + 31593797 = 31593906
139 + 31593767 = 31593906
263 + 31593643 = 31593906
277 + 31593629 = 31593906

Showing the first eight; more decompositions exist.
