Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726842, here are decompositions:

  • 41 + 8726801 = 8726842
  • 53 + 8726789 = 8726842
  • 83 + 8726759 = 8726842
  • 269 + 8726573 = 8726842
  • 461 + 8726381 = 8726842
  • 479 + 8726363 = 8726842
  • 491 + 8726351 = 8726842
  • 569 + 8726273 = 8726842

Showing the first eight; more decompositions exist.
