Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749020, here are decompositions:

  • 13 + 8749007 = 8749020
  • 19 + 8749001 = 8749020
  • 29 + 8748991 = 8749020
  • 31 + 8748989 = 8749020
  • 41 + 8748979 = 8749020
  • 47 + 8748973 = 8749020
  • 67 + 8748953 = 8749020
  • 127 + 8748893 = 8749020

Showing the first eight; more decompositions exist.
