Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443388, here are decompositions:

  • 31 + 2147443357 = 2147443388
  • 331 + 2147443057 = 2147443388
  • 367 + 2147443021 = 2147443388
  • 457 + 2147442931 = 2147443388
  • 487 + 2147442901 = 2147443388
  • 577 + 2147442811 = 2147443388
  • 691 + 2147442697 = 2147443388
  • 751 + 2147442637 = 2147443388

Showing the first eight; more decompositions exist.
