Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457248, here are decompositions:
- 47 + 31457201 = 31457248
- 89 + 31457159 = 31457248
- 149 + 31457099 = 31457248
- 167 + 31457081 = 31457248
- 197 + 31457051 = 31457248
- 239 + 31457009 = 31457248
- 311 + 31456937 = 31457248
- 419 + 31456829 = 31457248
Showing the first eight; more decompositions exist.
