Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21274, here are decompositions:
- 5 + 21269 = 21274
- 47 + 21227 = 21274
- 53 + 21221 = 21274
- 83 + 21191 = 21274
- 131 + 21143 = 21274
- 167 + 21107 = 21274
- 173 + 21101 = 21274
- 251 + 21023 = 21274
Showing the first eight; more decompositions exist.
