Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542060, here are decompositions:

  • 23 + 31542037 = 31542060
  • 29 + 31542031 = 31542060
  • 37 + 31542023 = 31542060
  • 47 + 31542013 = 31542060
  • 59 + 31542001 = 31542060
  • 71 + 31541989 = 31542060
  • 79 + 31541981 = 31542060
  • 83 + 31541977 = 31542060

Showing the first eight; more decompositions exist.
