Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469122, here are decompositions:

  • 151 + 2147468971 = 2147469122
  • 199 + 2147468923 = 2147469122
  • 241 + 2147468881 = 2147469122
  • 313 + 2147468809 = 2147469122
  • 349 + 2147468773 = 2147469122
  • 523 + 2147468599 = 2147469122
  • 619 + 2147468503 = 2147469122
  • 691 + 2147468431 = 2147469122

Showing the first eight; more decompositions exist.
