Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45388, here are decompositions:
- 11 + 45377 = 45388
- 47 + 45341 = 45388
- 59 + 45329 = 45388
- 71 + 45317 = 45388
- 107 + 45281 = 45388
- 191 + 45197 = 45388
- 197 + 45191 = 45388
- 227 + 45161 = 45388
Showing the first eight; more decompositions exist.
