Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611438, here are decompositions:

  • 5 + 8611433 = 8611438
  • 89 + 8611349 = 8611438
  • 107 + 8611331 = 8611438
  • 131 + 8611307 = 8611438
  • 137 + 8611301 = 8611438
  • 191 + 8611247 = 8611438
  • 257 + 8611181 = 8611438
  • 401 + 8611037 = 8611438

Showing the first eight; more decompositions exist.
