Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468562, here are decompositions:

  • 59 + 2147468503 = 2147468562
  • 131 + 2147468431 = 2147468562
  • 139 + 2147468423 = 2147468562
  • 271 + 2147468291 = 2147468562
  • 293 + 2147468269 = 2147468562
  • 313 + 2147468249 = 2147468562
  • 331 + 2147468231 = 2147468562
  • 373 + 2147468189 = 2147468562

Showing the first eight; more decompositions exist.
