Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637478, here are decompositions:

  • 11 + 8637467 = 8637478
  • 29 + 8637449 = 8637478
  • 137 + 8637341 = 8637478
  • 167 + 8637311 = 8637478
  • 251 + 8637227 = 8637478
  • 347 + 8637131 = 8637478
  • 359 + 8637119 = 8637478
  • 419 + 8637059 = 8637478

Showing the first eight; more decompositions exist.
