Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147582690, here are decompositions:

  • 157 + 2147582533 = 2147582690
  • 223 + 2147582467 = 2147582690
  • 229 + 2147582461 = 2147582690
  • 313 + 2147582377 = 2147582690
  • 367 + 2147582323 = 2147582690
  • 439 + 2147582251 = 2147582690
  • 541 + 2147582149 = 2147582690
  • 577 + 2147582113 = 2147582690

Showing the first eight; more decompositions exist.
