Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467890, here are decompositions:

  • 19 + 2147467871 = 2147467890
  • 89 + 2147467801 = 2147467890
  • 97 + 2147467793 = 2147467890
  • 131 + 2147467759 = 2147467890
  • 157 + 2147467733 = 2147467890
  • 173 + 2147467717 = 2147467890
  • 179 + 2147467711 = 2147467890
  • 193 + 2147467697 = 2147467890

Showing the first eight; more decompositions exist.
