Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668120, here are decompositions:

  • 47 + 8668073 = 8668120
  • 53 + 8668067 = 8668120
  • 59 + 8668061 = 8668120
  • 89 + 8668031 = 8668120
  • 191 + 8667929 = 8668120
  • 257 + 8667863 = 8668120
  • 311 + 8667809 = 8668120
  • 431 + 8667689 = 8668120

Showing the first eight; more decompositions exist.
