Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497928, here are decompositions:

  • 7 + 2147497921 = 2147497928
  • 157 + 2147497771 = 2147497928
  • 211 + 2147497717 = 2147497928
  • 229 + 2147497699 = 2147497928
  • 421 + 2147497507 = 2147497928
  • 439 + 2147497489 = 2147497928
  • 607 + 2147497321 = 2147497928
  • 691 + 2147497237 = 2147497928

Showing the first eight; more decompositions exist.
