Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670442, here are decompositions:

  • 71 + 8670371 = 8670442
  • 89 + 8670353 = 8670442
  • 251 + 8670191 = 8670442
  • 353 + 8670089 = 8670442
  • 401 + 8670041 = 8670442
  • 449 + 8669993 = 8670442
  • 461 + 8669981 = 8670442
  • 479 + 8669963 = 8670442

Showing the first eight; more decompositions exist.
