Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31352, here are decompositions:
- 19 + 31333 = 31352
- 31 + 31321 = 31352
- 103 + 31249 = 31352
- 163 + 31189 = 31352
- 193 + 31159 = 31352
- 199 + 31153 = 31352
- 229 + 31123 = 31352
- 271 + 31081 = 31352
Showing the first eight; more decompositions exist.
