Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471546, here are decompositions:
- 23 + 31471523 = 31471546
- 89 + 31471457 = 31471546
- 107 + 31471439 = 31471546
- 149 + 31471397 = 31471546
- 173 + 31471373 = 31471546
- 257 + 31471289 = 31471546
- 467 + 31471079 = 31471546
- 503 + 31471043 = 31471546
Showing the first eight; more decompositions exist.
