Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584590, here are decompositions:

  • 37 + 2147584553 = 2147584590
  • 61 + 2147584529 = 2147584590
  • 71 + 2147584519 = 2147584590
  • 89 + 2147584501 = 2147584590
  • 197 + 2147584393 = 2147584590
  • 199 + 2147584391 = 2147584590
  • 269 + 2147584321 = 2147584590
  • 313 + 2147584277 = 2147584590

Showing the first eight; more decompositions exist.
