Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294990100, here are decompositions:

  • 61 + 4294990039 = 4294990100
  • 97 + 4294990003 = 4294990100
  • 151 + 4294989949 = 4294990100
  • 157 + 4294989943 = 4294990100
  • 223 + 4294989877 = 4294990100
  • 283 + 4294989817 = 4294990100
  • 367 + 4294989733 = 4294990100
  • 397 + 4294989703 = 4294990100

Showing the first eight; more decompositions exist.
