Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295006840, here are decompositions:

  • 13 + 4295006827 = 4295006840
  • 67 + 4295006773 = 4295006840
  • 79 + 4295006761 = 4295006840
  • 97 + 4295006743 = 4295006840
  • 199 + 4295006641 = 4295006840
  • 211 + 4295006629 = 4295006840
  • 283 + 4295006557 = 4295006840
  • 307 + 4295006533 = 4295006840

Showing the first eight; more decompositions exist.
