Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974842, here are decompositions:

  • 31 + 4294974811 = 4294974842
  • 73 + 4294974769 = 4294974842
  • 349 + 4294974493 = 4294974842
  • 709 + 4294974133 = 4294974842
  • 853 + 4294973989 = 4294974842
  • 919 + 4294973923 = 4294974842
  • 1051 + 4294973791 = 4294974842
  • 1129 + 4294973713 = 4294974842

Showing the first eight; more decompositions exist.
