Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147380942, here are decompositions:

  • 23 + 2147380919 = 2147380942
  • 59 + 2147380883 = 2147380942
  • 89 + 2147380853 = 2147380942
  • 101 + 2147380841 = 2147380942
  • 131 + 2147380811 = 2147380942
  • 269 + 2147380673 = 2147380942
  • 293 + 2147380649 = 2147380942
  • 359 + 2147380583 = 2147380942

Showing the first eight; more decompositions exist.
