Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603318, here are decompositions:

  • 59 + 31603259 = 31603318
  • 179 + 31603139 = 31603318
  • 239 + 31603079 = 31603318
  • 359 + 31602959 = 31603318
  • 401 + 31602917 = 31603318
  • 419 + 31602899 = 31603318
  • 797 + 31602521 = 31603318
  • 821 + 31602497 = 31603318

Showing the first eight; more decompositions exist.
