Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547352, here are decompositions:
- 13 + 31547339 = 31547352
- 71 + 31547281 = 31547352
- 149 + 31547203 = 31547352
- 191 + 31547161 = 31547352
- 223 + 31547129 = 31547352
- 251 + 31547101 = 31547352
- 313 + 31547039 = 31547352
- 349 + 31547003 = 31547352
Showing the first eight; more decompositions exist.
