Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31196, here are decompositions:
- 3 + 31193 = 31196
- 7 + 31189 = 31196
- 13 + 31183 = 31196
- 19 + 31177 = 31196
- 37 + 31159 = 31196
- 43 + 31153 = 31196
- 73 + 31123 = 31196
- 127 + 31069 = 31196
Showing the first eight; more decompositions exist.
