Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747408, here are decompositions:

  • 79 + 8747329 = 8747408
  • 151 + 8747257 = 8747408
  • 157 + 8747251 = 8747408
  • 337 + 8747071 = 8747408
  • 367 + 8747041 = 8747408
  • 409 + 8746999 = 8747408
  • 487 + 8746921 = 8747408
  • 547 + 8746861 = 8747408

Showing the first eight; more decompositions exist.
