Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598570, here are decompositions:

  • 151 + 31598419 = 31598570
  • 193 + 31598377 = 31598570
  • 271 + 31598299 = 31598570
  • 331 + 31598239 = 31598570
  • 379 + 31598191 = 31598570
  • 433 + 31598137 = 31598570
  • 541 + 31598029 = 31598570
  • 643 + 31597927 = 31598570

Showing the first eight; more decompositions exist.
