Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987884, here are decompositions:

  • 37 + 4294987847 = 4294987884
  • 113 + 4294987771 = 4294987884
  • 127 + 4294987757 = 4294987884
  • 181 + 4294987703 = 4294987884
  • 233 + 4294987651 = 4294987884
  • 263 + 4294987621 = 4294987884
  • 277 + 4294987607 = 4294987884
  • 457 + 4294987427 = 4294987884

Showing the first eight; more decompositions exist.
