Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597714, here are decompositions:

17 + 31597697 = 31597714
41 + 31597673 = 31597714
101 + 31597613 = 31597714
173 + 31597541 = 31597714
347 + 31597367 = 31597714
431 + 31597283 = 31597714
461 + 31597253 = 31597714
563 + 31597151 = 31597714

Showing the first eight; more decompositions exist.
