Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977998, here are decompositions:

  • 7 + 4294977991 = 4294977998
  • 37 + 4294977961 = 4294977998
  • 139 + 4294977859 = 4294977998
  • 151 + 4294977847 = 4294977998
  • 211 + 4294977787 = 4294977998
  • 229 + 4294977769 = 4294977998
  • 331 + 4294977667 = 4294977998
  • 439 + 4294977559 = 4294977998

Showing the first eight; more decompositions exist.
