Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147573662, here are decompositions:

  • 5 + 2147573657 = 2147573662
  • 11 + 2147573651 = 2147573662
  • 53 + 2147573609 = 2147573662
  • 293 + 2147573369 = 2147573662
  • 401 + 2147573261 = 2147573662
  • 491 + 2147573171 = 2147573662
  • 593 + 2147573069 = 2147573662
  • 659 + 2147573003 = 2147573662

Showing the first eight; more decompositions exist.
