Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295072020, here are decompositions:

  • 23 + 4295071997 = 4295072020
  • 131 + 4295071889 = 4295072020
  • 149 + 4295071871 = 4295072020
  • 167 + 4295071853 = 4295072020
  • 233 + 4295071787 = 4295072020
  • 251 + 4295071769 = 4295072020
  • 263 + 4295071757 = 4295072020
  • 269 + 4295071751 = 4295072020

Showing the first eight; more decompositions exist.
