Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45472, here are decompositions:
- 59 + 45413 = 45472
- 83 + 45389 = 45472
- 131 + 45341 = 45472
- 179 + 45293 = 45472
- 191 + 45281 = 45472
- 239 + 45233 = 45472
- 281 + 45191 = 45472
- 293 + 45179 = 45472
Showing the first eight; more decompositions exist.
