Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978670, here are decompositions:

  • 43 + 4294978627 = 4294978670
  • 79 + 4294978591 = 4294978670
  • 181 + 4294978489 = 4294978670
  • 271 + 4294978399 = 4294978670
  • 337 + 4294978333 = 4294978670
  • 421 + 4294978249 = 4294978670
  • 439 + 4294978231 = 4294978670
  • 523 + 4294978147 = 4294978670

Showing the first eight; more decompositions exist.
