Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404642, here are decompositions:

  • 3 + 2147404639 = 2147404642
  • 23 + 2147404619 = 2147404642
  • 41 + 2147404601 = 2147404642
  • 59 + 2147404583 = 2147404642
  • 293 + 2147404349 = 2147404642
  • 311 + 2147404331 = 2147404642
  • 431 + 2147404211 = 2147404642
  • 521 + 2147404121 = 2147404642

Showing the first eight; more decompositions exist.
