Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294985640, here are decompositions:

  • 17 + 4294985623 = 4294985640
  • 59 + 4294985581 = 4294985640
  • 109 + 4294985531 = 4294985640
  • 149 + 4294985491 = 4294985640
  • 173 + 4294985467 = 4294985640
  • 181 + 4294985459 = 4294985640
  • 191 + 4294985449 = 4294985640
  • 241 + 4294985399 = 4294985640

Showing the first eight; more decompositions exist.
