Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700478, here are decompositions:

  • 5 + 8700473 = 8700478
  • 11 + 8700467 = 8700478
  • 29 + 8700449 = 8700478
  • 47 + 8700431 = 8700478
  • 71 + 8700407 = 8700478
  • 179 + 8700299 = 8700478
  • 191 + 8700287 = 8700478
  • 197 + 8700281 = 8700478

Showing the first eight; more decompositions exist.
