Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532020, here are decompositions:
- 17 + 31532003 = 31532020
- 53 + 31531967 = 31532020
- 89 + 31531931 = 31532020
- 137 + 31531883 = 31532020
- 269 + 31531751 = 31532020
- 293 + 31531727 = 31532020
- 353 + 31531667 = 31532020
- 563 + 31531457 = 31532020
Showing the first eight; more decompositions exist.
