Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622840, here are decompositions:

  • 29 + 8622811 = 8622840
  • 47 + 8622793 = 8622840
  • 59 + 8622781 = 8622840
  • 73 + 8622767 = 8622840
  • 157 + 8622683 = 8622840
  • 229 + 8622611 = 8622840
  • 263 + 8622577 = 8622840
  • 277 + 8622563 = 8622840

Showing the first eight; more decompositions exist.
