Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63420, here are decompositions:
- 11 + 63409 = 63420
- 23 + 63397 = 63420
- 29 + 63391 = 63420
- 31 + 63389 = 63420
- 43 + 63377 = 63420
- 53 + 63367 = 63420
- 59 + 63361 = 63420
- 67 + 63353 = 63420
Showing the first eight; more decompositions exist.
