Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97978, here are decompositions:

  • 5 + 97973 = 97978
  • 11 + 97967 = 97978
  • 17 + 97961 = 97978
  • 47 + 97931 = 97978
  • 59 + 97919 = 97978
  • 107 + 97871 = 97978
  • 131 + 97847 = 97978
  • 137 + 97841 = 97978

Showing the first eight; more decompositions exist.
