Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598352, here are decompositions:

31 + 31598321 = 31598352
53 + 31598299 = 31598352
73 + 31598279 = 31598352
113 + 31598239 = 31598352
139 + 31598213 = 31598352
151 + 31598201 = 31598352
173 + 31598179 = 31598352
211 + 31598141 = 31598352

Showing the first eight; more decompositions exist.
