Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478340, here are decompositions:

  • 41 + 2147478299 = 2147478340
  • 47 + 2147478293 = 2147478340
  • 191 + 2147478149 = 2147478340
  • 251 + 2147478089 = 2147478340
  • 257 + 2147478083 = 2147478340
  • 461 + 2147477879 = 2147478340
  • 467 + 2147477873 = 2147478340
  • 479 + 2147477861 = 2147478340

Showing the first eight; more decompositions exist.
