Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598406, here are decompositions:

5 + 31598401 = 31598406
29 + 31598377 = 31598406
43 + 31598363 = 31598406
53 + 31598353 = 31598406
79 + 31598327 = 31598406
107 + 31598299 = 31598406
127 + 31598279 = 31598406
139 + 31598267 = 31598406

Showing the first eight; more decompositions exist.
