Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527214, here are decompositions:
- 3 + 31527211 = 31527214
- 23 + 31527191 = 31527214
- 41 + 31527173 = 31527214
- 71 + 31527143 = 31527214
- 83 + 31527131 = 31527214
- 107 + 31527107 = 31527214
- 137 + 31527077 = 31527214
- 167 + 31527047 = 31527214
Showing the first eight; more decompositions exist.
