Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532492, here are decompositions:
- 3 + 31532489 = 31532492
- 139 + 31532353 = 31532492
- 151 + 31532341 = 31532492
- 163 + 31532329 = 31532492
- 223 + 31532269 = 31532492
- 283 + 31532209 = 31532492
- 379 + 31532113 = 31532492
- 421 + 31532071 = 31532492
Showing the first eight; more decompositions exist.
