Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598394, here are decompositions:

13 + 31598381 = 31598394
17 + 31598377 = 31598394
31 + 31598363 = 31598394
41 + 31598353 = 31598394
67 + 31598327 = 31598394
73 + 31598321 = 31598394
127 + 31598267 = 31598394
167 + 31598227 = 31598394

Showing the first eight; more decompositions exist.
