Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629578, here are decompositions:

  • 17 + 8629561 = 8629578
  • 71 + 8629507 = 8629578
  • 131 + 8629447 = 8629578
  • 137 + 8629441 = 8629578
  • 149 + 8629429 = 8629578
  • 229 + 8629349 = 8629578
  • 281 + 8629297 = 8629578
  • 337 + 8629241 = 8629578

Showing the first eight; more decompositions exist.
