Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659478, here are decompositions:

  • 7 + 8659471 = 8659478
  • 97 + 8659381 = 8659478
  • 127 + 8659351 = 8659478
  • 199 + 8659279 = 8659478
  • 271 + 8659207 = 8659478
  • 379 + 8659099 = 8659478
  • 547 + 8658931 = 8659478
  • 601 + 8658877 = 8659478

Showing the first eight; more decompositions exist.
