Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7538, here are decompositions:

  • 31 + 7507 = 7538
  • 61 + 7477 = 7538
  • 79 + 7459 = 7538
  • 127 + 7411 = 7538
  • 229 + 7309 = 7538
  • 241 + 7297 = 7538
  • 331 + 7207 = 7538
  • 379 + 7159 = 7538

Showing the first eight; more decompositions exist.
