Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749542, here are decompositions:

  • 73 + 8749469 = 8749542
  • 103 + 8749439 = 8749542
  • 199 + 8749343 = 8749542
  • 211 + 8749331 = 8749542
  • 233 + 8749309 = 8749542
  • 313 + 8749229 = 8749542
  • 379 + 8749163 = 8749542
  • 401 + 8749141 = 8749542

Showing the first eight; more decompositions exist.
