Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532284, here are decompositions:
- 5 + 31532279 = 31532284
- 23 + 31532261 = 31532284
- 167 + 31532117 = 31532284
- 263 + 31532021 = 31532284
- 281 + 31532003 = 31532284
- 317 + 31531967 = 31532284
- 353 + 31531931 = 31532284
- 401 + 31531883 = 31532284
Showing the first eight; more decompositions exist.
