Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594172, here are decompositions:

13 + 31594159 = 31594172
109 + 31594063 = 31594172
229 + 31593943 = 31594172
241 + 31593931 = 31594172
271 + 31593901 = 31594172
409 + 31593763 = 31594172
541 + 31593631 = 31594172
601 + 31593571 = 31594172

Showing the first eight; more decompositions exist.
