Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54978, here are decompositions:

  • 5 + 54973 = 54978
  • 19 + 54959 = 54978
  • 29 + 54949 = 54978
  • 37 + 54941 = 54978
  • 59 + 54919 = 54978
  • 61 + 54917 = 54978
  • 71 + 54907 = 54978
  • 97 + 54881 = 54978

Showing the first eight; more decompositions exist.
