Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957840, here are decompositions:

  • 59 + 4294957781 = 4294957840
  • 137 + 4294957703 = 4294957840
  • 197 + 4294957643 = 4294957840
  • 317 + 4294957523 = 4294957840
  • 347 + 4294957493 = 4294957840
  • 401 + 4294957439 = 4294957840
  • 443 + 4294957397 = 4294957840
  • 491 + 4294957349 = 4294957840

Showing the first eight; more decompositions exist.
