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.
