Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612858, here are decompositions:
- 5 + 31612853 = 31612858
- 131 + 31612727 = 31612858
- 191 + 31612667 = 31612858
- 197 + 31612661 = 31612858
- 239 + 31612619 = 31612858
- 269 + 31612589 = 31612858
- 311 + 31612547 = 31612858
- 467 + 31612391 = 31612858
Showing the first eight; more decompositions exist.
