Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536480, here are decompositions:
- 83 + 31536397 = 31536480
- 89 + 31536391 = 31536480
- 97 + 31536383 = 31536480
- 127 + 31536353 = 31536480
- 167 + 31536313 = 31536480
- 193 + 31536287 = 31536480
- 257 + 31536223 = 31536480
- 277 + 31536203 = 31536480
Showing the first eight; more decompositions exist.
