Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73978, here are decompositions:

  • 5 + 73973 = 73978
  • 17 + 73961 = 73978
  • 71 + 73907 = 73978
  • 101 + 73877 = 73978
  • 131 + 73847 = 73978
  • 227 + 73751 = 73978
  • 251 + 73727 = 73978
  • 257 + 73721 = 73978

Showing the first eight; more decompositions exist.
