Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147583788, here are decompositions:

  • 67 + 2147583721 = 2147583788
  • 79 + 2147583709 = 2147583788
  • 109 + 2147583679 = 2147583788
  • 157 + 2147583631 = 2147583788
  • 277 + 2147583511 = 2147583788
  • 307 + 2147583481 = 2147583788
  • 379 + 2147583409 = 2147583788
  • 397 + 2147583391 = 2147583788

Showing the first eight; more decompositions exist.
