Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657424, here are decompositions:

  • 37 + 8657387 = 8657424
  • 43 + 8657381 = 8657424
  • 47 + 8657377 = 8657424
  • 67 + 8657357 = 8657424
  • 101 + 8657323 = 8657424
  • 263 + 8657161 = 8657424
  • 313 + 8657111 = 8657424
  • 383 + 8657041 = 8657424

Showing the first eight; more decompositions exist.
