Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31650, here are decompositions:
- 7 + 31643 = 31650
- 23 + 31627 = 31650
- 43 + 31607 = 31650
- 67 + 31583 = 31650
- 83 + 31567 = 31650
- 103 + 31547 = 31650
- 107 + 31543 = 31650
- 109 + 31541 = 31650
Showing the first eight; more decompositions exist.
