Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532150, here are decompositions:
- 37 + 31532113 = 31532150
- 61 + 31532089 = 31532150
- 79 + 31532071 = 31532150
- 229 + 31531921 = 31532150
- 241 + 31531909 = 31532150
- 337 + 31531813 = 31532150
- 523 + 31531627 = 31532150
- 571 + 31531579 = 31532150
Showing the first eight; more decompositions exist.
