Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468178, here are decompositions:

  • 5 + 2147468173 = 2147468178
  • 47 + 2147468131 = 2147468178
  • 59 + 2147468119 = 2147468178
  • 109 + 2147468069 = 2147468178
  • 211 + 2147467967 = 2147468178
  • 257 + 2147467921 = 2147468178
  • 307 + 2147467871 = 2147468178
  • 409 + 2147467769 = 2147468178

Showing the first eight; more decompositions exist.
