Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666478, here are decompositions:

  • 19 + 8666459 = 8666478
  • 47 + 8666431 = 8666478
  • 59 + 8666419 = 8666478
  • 61 + 8666417 = 8666478
  • 97 + 8666381 = 8666478
  • 109 + 8666369 = 8666478
  • 127 + 8666351 = 8666478
  • 131 + 8666347 = 8666478

Showing the first eight; more decompositions exist.
