Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623410, here are decompositions:
- 37 + 31623373 = 31623410
- 67 + 31623343 = 31623410
- 73 + 31623337 = 31623410
- 199 + 31623211 = 31623410
- 211 + 31623199 = 31623410
- 229 + 31623181 = 31623410
- 241 + 31623169 = 31623410
- 349 + 31623061 = 31623410
Showing the first eight; more decompositions exist.
