Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970990, here are decompositions:

  • 67 + 4294970923 = 4294970990
  • 127 + 4294970863 = 4294970990
  • 151 + 4294970839 = 4294970990
  • 229 + 4294970761 = 4294970990
  • 241 + 4294970749 = 4294970990
  • 421 + 4294970569 = 4294970990
  • 487 + 4294970503 = 4294970990
  • 523 + 4294970467 = 4294970990

Showing the first eight; more decompositions exist.
