Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500280, here are decompositions:

  • 97 + 2147500183 = 2147500280
  • 103 + 2147500177 = 2147500280
  • 157 + 2147500123 = 2147500280
  • 199 + 2147500081 = 2147500280
  • 283 + 2147499997 = 2147500280
  • 397 + 2147499883 = 2147500280
  • 439 + 2147499841 = 2147500280
  • 577 + 2147499703 = 2147500280

Showing the first eight; more decompositions exist.
