Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31206, here are decompositions:
- 13 + 31193 = 31206
- 17 + 31189 = 31206
- 23 + 31183 = 31206
- 29 + 31177 = 31206
- 47 + 31159 = 31206
- 53 + 31153 = 31206
- 59 + 31147 = 31206
- 67 + 31139 = 31206
Showing the first eight; more decompositions exist.
