Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467848, here are decompositions:

  • 47 + 2147467801 = 2147467848
  • 79 + 2147467769 = 2147467848
  • 89 + 2147467759 = 2147467848
  • 101 + 2147467747 = 2147467848
  • 131 + 2147467717 = 2147467848
  • 137 + 2147467711 = 2147467848
  • 151 + 2147467697 = 2147467848
  • 179 + 2147467669 = 2147467848

Showing the first eight; more decompositions exist.
