Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667838, here are decompositions:

  • 17 + 8667821 = 8667838
  • 29 + 8667809 = 8667838
  • 41 + 8667797 = 8667838
  • 131 + 8667707 = 8667838
  • 149 + 8667689 = 8667838
  • 197 + 8667641 = 8667838
  • 227 + 8667611 = 8667838
  • 317 + 8667521 = 8667838

Showing the first eight; more decompositions exist.
