Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597554, here are decompositions:

5 + 31597549 = 31597554
13 + 31597541 = 31597554
47 + 31597507 = 31597554
61 + 31597493 = 31597554
71 + 31597483 = 31597554
83 + 31597471 = 31597554
101 + 31597453 = 31597554
137 + 31597417 = 31597554

Showing the first eight; more decompositions exist.
