Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147372580, here are decompositions:

  • 29 + 2147372551 = 2147372580
  • 37 + 2147372543 = 2147372580
  • 113 + 2147372467 = 2147372580
  • 251 + 2147372329 = 2147372580
  • 307 + 2147372273 = 2147372580
  • 349 + 2147372231 = 2147372580
  • 401 + 2147372179 = 2147372580
  • 433 + 2147372147 = 2147372580

Showing the first eight; more decompositions exist.
