Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620106, here are decompositions:

  • 47 + 31620059 = 31620106
  • 113 + 31619993 = 31620106
  • 257 + 31619849 = 31620106
  • 263 + 31619843 = 31620106
  • 317 + 31619789 = 31620106
  • 347 + 31619759 = 31620106
  • 383 + 31619723 = 31620106
  • 389 + 31619717 = 31620106

Showing the first eight; more decompositions exist.
