Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598494, here are decompositions:

71 + 31598423 = 31598494
113 + 31598381 = 31598494
131 + 31598363 = 31598494
167 + 31598327 = 31598494
173 + 31598321 = 31598494
227 + 31598267 = 31598494
233 + 31598261 = 31598494
281 + 31598213 = 31598494

Showing the first eight; more decompositions exist.
