Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538324, here are decompositions:
- 73 + 31538251 = 31538324
- 163 + 31538161 = 31538324
- 193 + 31538131 = 31538324
- 211 + 31538113 = 31538324
- 271 + 31538053 = 31538324
- 277 + 31538047 = 31538324
- 421 + 31537903 = 31538324
- 463 + 31537861 = 31538324
Showing the first eight; more decompositions exist.
