Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147541982, here are decompositions:

  • 29 + 2147541953 = 2147541982
  • 41 + 2147541941 = 2147541982
  • 233 + 2147541749 = 2147541982
  • 239 + 2147541743 = 2147541982
  • 269 + 2147541713 = 2147541982
  • 281 + 2147541701 = 2147541982
  • 359 + 2147541623 = 2147541982
  • 389 + 2147541593 = 2147541982

Showing the first eight; more decompositions exist.
