Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597622, here are decompositions:

19 + 31597603 = 31597622
73 + 31597549 = 31597622
139 + 31597483 = 31597622
151 + 31597471 = 31597622
211 + 31597411 = 31597622
379 + 31597243 = 31597622
409 + 31597213 = 31597622
523 + 31597099 = 31597622

Showing the first eight; more decompositions exist.
