Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970778, here are decompositions:

  • 17 + 4294970761 = 4294970778
  • 29 + 4294970749 = 4294970778
  • 211 + 4294970567 = 4294970778
  • 257 + 4294970521 = 4294970778
  • 311 + 4294970467 = 4294970778
  • 401 + 4294970377 = 4294970778
  • 431 + 4294970347 = 4294970778
  • 547 + 4294970231 = 4294970778

Showing the first eight; more decompositions exist.
