Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742448, here are decompositions:

  • 47 + 8742401 = 8742448
  • 89 + 8742359 = 8742448
  • 101 + 8742347 = 8742448
  • 131 + 8742317 = 8742448
  • 251 + 8742197 = 8742448
  • 389 + 8742059 = 8742448
  • 461 + 8741987 = 8742448
  • 587 + 8741861 = 8742448

Showing the first eight; more decompositions exist.
