Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741988, here are decompositions:

  • 5 + 8741983 = 8741988
  • 11 + 8741977 = 8741988
  • 37 + 8741951 = 8741988
  • 41 + 8741947 = 8741988
  • 127 + 8741861 = 8741988
  • 149 + 8741839 = 8741988
  • 191 + 8741797 = 8741988
  • 239 + 8741749 = 8741988

Showing the first eight; more decompositions exist.
