Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147548342, here are decompositions:

  • 29 + 2147548313 = 2147548342
  • 41 + 2147548301 = 2147548342
  • 83 + 2147548259 = 2147548342
  • 113 + 2147548229 = 2147548342
  • 131 + 2147548211 = 2147548342
  • 431 + 2147547911 = 2147548342
  • 509 + 2147547833 = 2147548342
  • 809 + 2147547533 = 2147548342

Showing the first eight; more decompositions exist.
