Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532138, here are decompositions:
- 67 + 31532071 = 31532138
- 229 + 31531909 = 31532138
- 499 + 31531639 = 31532138
- 739 + 31531399 = 31532138
- 769 + 31531369 = 31532138
- 877 + 31531261 = 31532138
- 1021 + 31531117 = 31532138
- 1039 + 31531099 = 31532138
Showing the first eight; more decompositions exist.
