Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978492, here are decompositions:

  • 3 + 4294978489 = 4294978492
  • 131 + 4294978361 = 4294978492
  • 179 + 4294978313 = 4294978492
  • 269 + 4294978223 = 4294978492
  • 281 + 4294978211 = 4294978492
  • 359 + 4294978133 = 4294978492
  • 401 + 4294978091 = 4294978492
  • 503 + 4294977989 = 4294978492

Showing the first eight; more decompositions exist.
