Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642600, here are decompositions:

  • 19 + 8642581 = 8642600
  • 67 + 8642533 = 8642600
  • 151 + 8642449 = 8642600
  • 271 + 8642329 = 8642600
  • 523 + 8642077 = 8642600
  • 541 + 8642059 = 8642600
  • 613 + 8641987 = 8642600
  • 643 + 8641957 = 8642600

Showing the first eight; more decompositions exist.
