Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709490, here are decompositions:

  • 29 + 8709461 = 8709490
  • 47 + 8709443 = 8709490
  • 59 + 8709431 = 8709490
  • 107 + 8709383 = 8709490
  • 113 + 8709377 = 8709490
  • 173 + 8709317 = 8709490
  • 191 + 8709299 = 8709490
  • 233 + 8709257 = 8709490

Showing the first eight; more decompositions exist.
