Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598382, here are decompositions:

5 + 31598377 = 31598382
19 + 31598363 = 31598382
29 + 31598353 = 31598382
61 + 31598321 = 31598382
83 + 31598299 = 31598382
103 + 31598279 = 31598382
181 + 31598201 = 31598382
191 + 31598191 = 31598382

Showing the first eight; more decompositions exist.
