Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468148, here are decompositions:

  • 17 + 2147468131 = 2147468148
  • 29 + 2147468119 = 2147468148
  • 79 + 2147468069 = 2147468148
  • 181 + 2147467967 = 2147468148
  • 227 + 2147467921 = 2147468148
  • 229 + 2147467919 = 2147468148
  • 277 + 2147467871 = 2147468148
  • 347 + 2147467801 = 2147468148

Showing the first eight; more decompositions exist.
