Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611490, here are decompositions:

  • 3 + 8611487 = 8611490
  • 67 + 8611423 = 8611490
  • 79 + 8611411 = 8611490
  • 109 + 8611381 = 8611490
  • 193 + 8611297 = 8611490
  • 229 + 8611261 = 8611490
  • 241 + 8611249 = 8611490
  • 271 + 8611219 = 8611490

Showing the first eight; more decompositions exist.
