Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598448, here are decompositions:

29 + 31598419 = 31598448
31 + 31598417 = 31598448
47 + 31598401 = 31598448
67 + 31598381 = 31598448
71 + 31598377 = 31598448
127 + 31598321 = 31598448
149 + 31598299 = 31598448
181 + 31598267 = 31598448

Showing the first eight; more decompositions exist.
