Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468838, here are decompositions:

  • 5 + 2147468833 = 2147468838
  • 29 + 2147468809 = 2147468838
  • 37 + 2147468801 = 2147468838
  • 59 + 2147468779 = 2147468838
  • 199 + 2147468639 = 2147468838
  • 239 + 2147468599 = 2147468838
  • 331 + 2147468507 = 2147468838
  • 409 + 2147468429 = 2147468838

Showing the first eight; more decompositions exist.
