Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497844, here are decompositions:

  • 73 + 2147497771 = 2147497844
  • 127 + 2147497717 = 2147497844
  • 181 + 2147497663 = 2147497844
  • 337 + 2147497507 = 2147497844
  • 397 + 2147497447 = 2147497844
  • 433 + 2147497411 = 2147497844
  • 523 + 2147497321 = 2147497844
  • 601 + 2147497243 = 2147497844

Showing the first eight; more decompositions exist.
