Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598350, here are decompositions:

23 + 31598327 = 31598350
29 + 31598321 = 31598350
71 + 31598279 = 31598350
83 + 31598267 = 31598350
89 + 31598261 = 31598350
137 + 31598213 = 31598350
149 + 31598201 = 31598350
293 + 31598057 = 31598350

Showing the first eight; more decompositions exist.
