Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532166, here are decompositions:
- 53 + 31532113 = 31532166
- 103 + 31532063 = 31532166
- 163 + 31532003 = 31532166
- 199 + 31531967 = 31532166
- 257 + 31531909 = 31532166
- 283 + 31531883 = 31532166
- 349 + 31531817 = 31532166
- 353 + 31531813 = 31532166
Showing the first eight; more decompositions exist.
