Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295071920, here are decompositions:

  • 11 + 4295071909 = 4295071920
  • 17 + 4295071903 = 4295071920
  • 31 + 4295071889 = 4295071920
  • 67 + 4295071853 = 4295071920
  • 131 + 4295071789 = 4295071920
  • 151 + 4295071769 = 4295071920
  • 163 + 4295071757 = 4295071920
  • 179 + 4295071741 = 4295071920

Showing the first eight; more decompositions exist.
