Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603360, here are decompositions:

  • 17 + 31603343 = 31603360
  • 101 + 31603259 = 31603360
  • 167 + 31603193 = 31603360
  • 251 + 31603109 = 31603360
  • 281 + 31603079 = 31603360
  • 401 + 31602959 = 31603360
  • 443 + 31602917 = 31603360
  • 461 + 31602899 = 31603360

Showing the first eight; more decompositions exist.
