Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598460, here are decompositions:

11 + 31598449 = 31598460
37 + 31598423 = 31598460
41 + 31598419 = 31598460
43 + 31598417 = 31598460
59 + 31598401 = 31598460
79 + 31598381 = 31598460
83 + 31598377 = 31598460
97 + 31598363 = 31598460

Showing the first eight; more decompositions exist.
