Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761790, here are decompositions:

  • 151 + 8761639 = 8761790
  • 157 + 8761633 = 8761790
  • 283 + 8761507 = 8761790
  • 337 + 8761453 = 8761790
  • 463 + 8761327 = 8761790
  • 487 + 8761303 = 8761790
  • 547 + 8761243 = 8761790
  • 577 + 8761213 = 8761790

Showing the first eight; more decompositions exist.
