Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597954, here are decompositions:

41 + 31597913 = 31597954
131 + 31597823 = 31597954
191 + 31597763 = 31597954
233 + 31597721 = 31597954
257 + 31597697 = 31597954
281 + 31597673 = 31597954
383 + 31597571 = 31597954
461 + 31597493 = 31597954

Showing the first eight; more decompositions exist.
