Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538234, here are decompositions:
- 31 + 31538203 = 31538234
- 73 + 31538161 = 31538234
- 97 + 31538137 = 31538234
- 103 + 31538131 = 31538234
- 127 + 31538107 = 31538234
- 163 + 31538071 = 31538234
- 181 + 31538053 = 31538234
- 313 + 31537921 = 31538234
Showing the first eight; more decompositions exist.
