Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497368, here are decompositions:

  • 7 + 2147497361 = 2147497368
  • 19 + 2147497349 = 2147497368
  • 47 + 2147497321 = 2147497368
  • 131 + 2147497237 = 2147497368
  • 167 + 2147497201 = 2147497368
  • 227 + 2147497141 = 2147497368
  • 349 + 2147497019 = 2147497368
  • 389 + 2147496979 = 2147497368

Showing the first eight; more decompositions exist.
