Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521792, here are decompositions:

  • 3 + 521789 = 521792
  • 43 + 521749 = 521792
  • 151 + 521641 = 521792
  • 211 + 521581 = 521792
  • 241 + 521551 = 521792
  • 433 + 521359 = 521792
  • 463 + 521329 = 521792
  • 541 + 521251 = 521792

Showing the first eight; more decompositions exist.
