Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719478, here are decompositions:

  • 37 + 8719441 = 8719478
  • 151 + 8719327 = 8719478
  • 337 + 8719141 = 8719478
  • 379 + 8719099 = 8719478
  • 421 + 8719057 = 8719478
  • 457 + 8719021 = 8719478
  • 571 + 8718907 = 8719478
  • 601 + 8718877 = 8719478

Showing the first eight; more decompositions exist.
