Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612432, here are decompositions:
- 3 + 31612429 = 31612432
- 41 + 31612391 = 31612432
- 191 + 31612241 = 31612432
- 233 + 31612199 = 31612432
- 281 + 31612151 = 31612432
- 311 + 31612121 = 31612432
- 353 + 31612079 = 31612432
- 389 + 31612043 = 31612432
Showing the first eight; more decompositions exist.
