Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611138, here are decompositions:

  • 5 + 8611133 = 8611138
  • 101 + 8611037 = 8611138
  • 257 + 8610881 = 8611138
  • 311 + 8610827 = 8611138
  • 401 + 8610737 = 8611138
  • 479 + 8610659 = 8611138
  • 521 + 8610617 = 8611138
  • 617 + 8610521 = 8611138

Showing the first eight; more decompositions exist.
