Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526164, here are decompositions:

  • 23 + 31526141 = 31526164
  • 101 + 31526063 = 31526164
  • 107 + 31526057 = 31526164
  • 113 + 31526051 = 31526164
  • 251 + 31525913 = 31526164
  • 347 + 31525817 = 31526164
  • 353 + 31525811 = 31526164
  • 401 + 31525763 = 31526164

Showing the first eight; more decompositions exist.
