Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637722, here are decompositions:

  • 103 + 8637619 = 8637722
  • 199 + 8637523 = 8637722
  • 229 + 8637493 = 8637722
  • 241 + 8637481 = 8637722
  • 271 + 8637451 = 8637722
  • 349 + 8637373 = 8637722
  • 421 + 8637301 = 8637722
  • 433 + 8637289 = 8637722

Showing the first eight; more decompositions exist.
