Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526174, here are decompositions:

  • 193 + 31525981 = 31526174
  • 223 + 31525951 = 31526174
  • 271 + 31525903 = 31526174
  • 283 + 31525891 = 31526174
  • 397 + 31525777 = 31526174
  • 457 + 31525717 = 31526174
  • 487 + 31525687 = 31526174
  • 523 + 31525651 = 31526174

Showing the first eight; more decompositions exist.
