Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91538, here are decompositions:

  • 79 + 91459 = 91538
  • 127 + 91411 = 91538
  • 151 + 91387 = 91538
  • 157 + 91381 = 91538
  • 229 + 91309 = 91538
  • 241 + 91297 = 91538
  • 379 + 91159 = 91538
  • 397 + 91141 = 91538

Showing the first eight; more decompositions exist.
