Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469042, here are decompositions:

  • 41 + 2147469001 = 2147469042
  • 71 + 2147468971 = 2147469042
  • 109 + 2147468933 = 2147469042
  • 181 + 2147468861 = 2147469042
  • 233 + 2147468809 = 2147469042
  • 239 + 2147468803 = 2147469042
  • 241 + 2147468801 = 2147469042
  • 263 + 2147468779 = 2147469042

Showing the first eight; more decompositions exist.
