Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710780, here are decompositions:

  • 47 + 8710733 = 8710780
  • 53 + 8710727 = 8710780
  • 101 + 8710679 = 8710780
  • 131 + 8710649 = 8710780
  • 149 + 8710631 = 8710780
  • 191 + 8710589 = 8710780
  • 233 + 8710547 = 8710780
  • 251 + 8710529 = 8710780

Showing the first eight; more decompositions exist.
