Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538244, here are decompositions:
- 5 + 31538239 = 31538244
- 37 + 31538207 = 31538244
- 41 + 31538203 = 31538244
- 83 + 31538161 = 31538244
- 103 + 31538141 = 31538244
- 107 + 31538137 = 31538244
- 113 + 31538131 = 31538244
- 131 + 31538113 = 31538244
Showing the first eight; more decompositions exist.
