Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598584, here are decompositions:

41 + 31598543 = 31598584
47 + 31598537 = 31598584
71 + 31598513 = 31598584
167 + 31598417 = 31598584
257 + 31598327 = 31598584
263 + 31598321 = 31598584
317 + 31598267 = 31598584
383 + 31598201 = 31598584

Showing the first eight; more decompositions exist.
