Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546, here are decompositions:
- 3 + 31543 = 31546
- 5 + 31541 = 31546
- 29 + 31517 = 31546
- 149 + 31397 = 31546
- 167 + 31379 = 31546
- 227 + 31319 = 31546
- 239 + 31307 = 31546
- 269 + 31277 = 31546
Showing the first eight; more decompositions exist.
