Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471258, here are decompositions:
- 41 + 31471217 = 31471258
- 149 + 31471109 = 31471258
- 167 + 31471091 = 31471258
- 179 + 31471079 = 31471258
- 227 + 31471031 = 31471258
- 251 + 31471007 = 31471258
- 257 + 31471001 = 31471258
- 281 + 31470977 = 31471258
Showing the first eight; more decompositions exist.
