Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584292, here are decompositions:
- 11 + 31584281 = 31584292
- 29 + 31584263 = 31584292
- 59 + 31584233 = 31584292
- 101 + 31584191 = 31584292
- 149 + 31584143 = 31584292
- 191 + 31584101 = 31584292
- 293 + 31583999 = 31584292
- 461 + 31583831 = 31584292
Showing the first eight; more decompositions exist.
