Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598262, here are decompositions:

23 + 31598239 = 31598262
61 + 31598201 = 31598262
71 + 31598191 = 31598262
83 + 31598179 = 31598262
229 + 31598033 = 31598262
233 + 31598029 = 31598262
251 + 31598011 = 31598262
349 + 31597913 = 31598262

Showing the first eight; more decompositions exist.
