Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545248, here are decompositions:
- 37 + 31545211 = 31545248
- 67 + 31545181 = 31545248
- 151 + 31545097 = 31545248
- 157 + 31545091 = 31545248
- 181 + 31545067 = 31545248
- 199 + 31545049 = 31545248
- 307 + 31544941 = 31545248
- 349 + 31544899 = 31545248
Showing the first eight; more decompositions exist.
