Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977620, here are decompositions:

  • 61 + 4294977559 = 4294977620
  • 97 + 4294977523 = 4294977620
  • 139 + 4294977481 = 4294977620
  • 229 + 4294977391 = 4294977620
  • 457 + 4294977163 = 4294977620
  • 523 + 4294977097 = 4294977620
  • 541 + 4294977079 = 4294977620
  • 643 + 4294976977 = 4294977620

Showing the first eight; more decompositions exist.
