Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707578, here are decompositions:

  • 41 + 8707537 = 8707578
  • 101 + 8707477 = 8707578
  • 149 + 8707429 = 8707578
  • 157 + 8707421 = 8707578
  • 199 + 8707379 = 8707578
  • 227 + 8707351 = 8707578
  • 251 + 8707327 = 8707578
  • 337 + 8707241 = 8707578

Showing the first eight; more decompositions exist.
