Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978156, here are decompositions:

  • 23 + 4294978133 = 4294978156
  • 89 + 4294978067 = 4294978156
  • 167 + 4294977989 = 4294978156
  • 257 + 4294977899 = 4294978156
  • 263 + 4294977893 = 4294978156
  • 317 + 4294977839 = 4294978156
  • 653 + 4294977503 = 4294978156
  • 743 + 4294977413 = 4294978156

Showing the first eight; more decompositions exist.
