Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375290, here are decompositions:

  • 41 + 2147375249 = 2147375290
  • 83 + 2147375207 = 2147375290
  • 89 + 2147375201 = 2147375290
  • 149 + 2147375141 = 2147375290
  • 191 + 2147375099 = 2147375290
  • 239 + 2147375051 = 2147375290
  • 293 + 2147374997 = 2147375290
  • 443 + 2147374847 = 2147375290

Showing the first eight; more decompositions exist.
