Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597994, here are decompositions:

7 + 31597987 = 31597994
61 + 31597933 = 31597994
67 + 31597927 = 31597994
151 + 31597843 = 31597994
193 + 31597801 = 31597994
277 + 31597717 = 31597994
487 + 31597507 = 31597994
523 + 31597471 = 31597994

Showing the first eight; more decompositions exist.
