Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147495408, here are decompositions:

  • 7 + 2147495401 = 2147495408
  • 61 + 2147495347 = 2147495408
  • 577 + 2147494831 = 2147495408
  • 1039 + 2147494369 = 2147495408
  • 1051 + 2147494357 = 2147495408
  • 1201 + 2147494207 = 2147495408
  • 1249 + 2147494159 = 2147495408
  • 1321 + 2147494087 = 2147495408

Showing the first eight; more decompositions exist.
