Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90434, here are decompositions:

  • 31 + 90403 = 90434
  • 37 + 90397 = 90434
  • 61 + 90373 = 90434
  • 163 + 90271 = 90434
  • 271 + 90163 = 90434
  • 307 + 90127 = 90434
  • 313 + 90121 = 90434
  • 367 + 90067 = 90434

Showing the first eight; more decompositions exist.
