Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598466, here are decompositions:

7 + 31598459 = 31598466
17 + 31598449 = 31598466
43 + 31598423 = 31598466
47 + 31598419 = 31598466
89 + 31598377 = 31598466
103 + 31598363 = 31598466
113 + 31598353 = 31598466
139 + 31598327 = 31598466

Showing the first eight; more decompositions exist.
