Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977912, here are decompositions:

  • 13 + 4294977899 = 4294977912
  • 19 + 4294977893 = 4294977912
  • 31 + 4294977881 = 4294977912
  • 53 + 4294977859 = 4294977912
  • 73 + 4294977839 = 4294977912
  • 89 + 4294977823 = 4294977912
  • 149 + 4294977763 = 4294977912
  • 151 + 4294977761 = 4294977912

Showing the first eight; more decompositions exist.
