Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987920, here are decompositions:

  • 17 + 4294987903 = 4294987920
  • 31 + 4294987889 = 4294987920
  • 61 + 4294987859 = 4294987920
  • 71 + 4294987849 = 4294987920
  • 73 + 4294987847 = 4294987920
  • 149 + 4294987771 = 4294987920
  • 151 + 4294987769 = 4294987920
  • 163 + 4294987757 = 4294987920

Showing the first eight; more decompositions exist.
