Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448346, here are decompositions:
- 23 + 31448323 = 31448346
- 37 + 31448309 = 31448346
- 43 + 31448303 = 31448346
- 47 + 31448299 = 31448346
- 53 + 31448293 = 31448346
- 113 + 31448233 = 31448346
- 197 + 31448149 = 31448346
- 277 + 31448069 = 31448346
Showing the first eight; more decompositions exist.
