Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562534, here are decompositions:

  • 67 + 31562467 = 31562534
  • 103 + 31562431 = 31562534
  • 271 + 31562263 = 31562534
  • 277 + 31562257 = 31562534
  • 397 + 31562137 = 31562534
  • 541 + 31561993 = 31562534
  • 607 + 31561927 = 31562534
  • 631 + 31561903 = 31562534

Showing the first eight; more decompositions exist.
