Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702090, here are decompositions:

  • 139 + 8701951 = 8702090
  • 157 + 8701933 = 8702090
  • 277 + 8701813 = 8702090
  • 349 + 8701741 = 8702090
  • 367 + 8701723 = 8702090
  • 433 + 8701657 = 8702090
  • 571 + 8701519 = 8702090
  • 601 + 8701489 = 8702090

Showing the first eight; more decompositions exist.
