Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987720, here are decompositions:

  • 17 + 4294987703 = 4294987720
  • 113 + 4294987607 = 4294987720
  • 131 + 4294987589 = 4294987720
  • 197 + 4294987523 = 4294987720
  • 293 + 4294987427 = 4294987720
  • 389 + 4294987331 = 4294987720
  • 431 + 4294987289 = 4294987720
  • 563 + 4294987157 = 4294987720

Showing the first eight; more decompositions exist.
