Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598370, here are decompositions:

7 + 31598363 = 31598370
17 + 31598353 = 31598370
43 + 31598327 = 31598370
71 + 31598299 = 31598370
103 + 31598267 = 31598370
109 + 31598261 = 31598370
131 + 31598239 = 31598370
157 + 31598213 = 31598370

Showing the first eight; more decompositions exist.
