Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469844, here are decompositions:

  • 251 + 2147469593 = 2147469844
  • 353 + 2147469491 = 2147469844
  • 743 + 2147469101 = 2147469844
  • 797 + 2147469047 = 2147469844
  • 827 + 2147469017 = 2147469844
  • 857 + 2147468987 = 2147469844
  • 911 + 2147468933 = 2147469844
  • 983 + 2147468861 = 2147469844

Showing the first eight; more decompositions exist.
