Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738740, here are decompositions:

  • 11 + 8738729 = 8738740
  • 29 + 8738711 = 8738740
  • 149 + 8738591 = 8738740
  • 173 + 8738567 = 8738740
  • 233 + 8738507 = 8738740
  • 293 + 8738447 = 8738740
  • 389 + 8738351 = 8738740
  • 401 + 8738339 = 8738740

Showing the first eight; more decompositions exist.
