Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712488, here are decompositions:

  • 67 + 8712421 = 8712488
  • 139 + 8712349 = 8712488
  • 151 + 8712337 = 8712488
  • 181 + 8712307 = 8712488
  • 229 + 8712259 = 8712488
  • 307 + 8712181 = 8712488
  • 331 + 8712157 = 8712488
  • 397 + 8712091 = 8712488

Showing the first eight; more decompositions exist.
