Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598392, here are decompositions:

11 + 31598381 = 31598392
29 + 31598363 = 31598392
71 + 31598321 = 31598392
113 + 31598279 = 31598392
131 + 31598261 = 31598392
179 + 31598213 = 31598392
191 + 31598201 = 31598392
251 + 31598141 = 31598392

Showing the first eight; more decompositions exist.
