Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532190, here are decompositions:
- 23 + 31532167 = 31532190
- 73 + 31532117 = 31532190
- 101 + 31532089 = 31532190
- 127 + 31532063 = 31532190
- 223 + 31531967 = 31532190
- 269 + 31531921 = 31532190
- 281 + 31531909 = 31532190
- 307 + 31531883 = 31532190
Showing the first eight; more decompositions exist.
