Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153478, here are decompositions:
- 29 + 153449 = 153478
- 41 + 153437 = 153478
- 71 + 153407 = 153478
- 107 + 153371 = 153478
- 191 + 153287 = 153478
- 197 + 153281 = 153478
- 389 + 153089 = 153478
- 401 + 153077 = 153478
Showing the first eight; more decompositions exist.
