Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977980, here are decompositions:

  • 19 + 4294977961 = 4294977980
  • 37 + 4294977943 = 4294977980
  • 157 + 4294977823 = 4294977980
  • 193 + 4294977787 = 4294977980
  • 211 + 4294977769 = 4294977980
  • 229 + 4294977751 = 4294977980
  • 313 + 4294977667 = 4294977980
  • 409 + 4294977571 = 4294977980

Showing the first eight; more decompositions exist.
