Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545282, here are decompositions:
- 61 + 31545221 = 31545282
- 71 + 31545211 = 31545282
- 101 + 31545181 = 31545282
- 163 + 31545119 = 31545282
- 191 + 31545091 = 31545282
- 199 + 31545083 = 31545282
- 233 + 31545049 = 31545282
- 281 + 31545001 = 31545282
Showing the first eight; more decompositions exist.
