Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102472, here are decompositions:
- 11 + 102461 = 102472
- 113 + 102359 = 102472
- 173 + 102299 = 102472
- 179 + 102293 = 102472
- 239 + 102233 = 102472
- 269 + 102203 = 102472
- 281 + 102191 = 102472
- 311 + 102161 = 102472
Showing the first eight; more decompositions exist.
