Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468442, here are decompositions:

  • 11 + 2147468431 = 2147468442
  • 13 + 2147468429 = 2147468442
  • 19 + 2147468423 = 2147468442
  • 101 + 2147468341 = 2147468442
  • 151 + 2147468291 = 2147468442
  • 173 + 2147468269 = 2147468442
  • 193 + 2147468249 = 2147468442
  • 211 + 2147468231 = 2147468442

Showing the first eight; more decompositions exist.
