Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475270, here are decompositions:
- 19 + 31475251 = 31475270
- 61 + 31475209 = 31475270
- 139 + 31475131 = 31475270
- 163 + 31475107 = 31475270
- 181 + 31475089 = 31475270
- 199 + 31475071 = 31475270
- 241 + 31475029 = 31475270
- 271 + 31474999 = 31475270
Showing the first eight; more decompositions exist.
