Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598328, here are decompositions:

7 + 31598321 = 31598328
29 + 31598299 = 31598328
61 + 31598267 = 31598328
67 + 31598261 = 31598328
89 + 31598239 = 31598328
101 + 31598227 = 31598328
127 + 31598201 = 31598328
137 + 31598191 = 31598328

Showing the first eight; more decompositions exist.
