Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53978, here are decompositions:

  • 19 + 53959 = 53978
  • 61 + 53917 = 53978
  • 79 + 53899 = 53978
  • 97 + 53881 = 53978
  • 349 + 53629 = 53978
  • 367 + 53611 = 53978
  • 409 + 53569 = 53978
  • 499 + 53479 = 53978

Showing the first eight; more decompositions exist.
