Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443804, here are decompositions:

  • 5 + 2147443799 = 2147443804
  • 17 + 2147443787 = 2147443804
  • 83 + 2147443721 = 2147443804
  • 257 + 2147443547 = 2147443804
  • 281 + 2147443523 = 2147443804
  • 383 + 2147443421 = 2147443804
  • 431 + 2147443373 = 2147443804
  • 461 + 2147443343 = 2147443804

Showing the first eight; more decompositions exist.
