Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598590, here are decompositions:

47 + 31598543 = 31598590
53 + 31598537 = 31598590
71 + 31598519 = 31598590
131 + 31598459 = 31598590
167 + 31598423 = 31598590
173 + 31598417 = 31598590
227 + 31598363 = 31598590
263 + 31598327 = 31598590

Showing the first eight; more decompositions exist.
