Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526378, here are decompositions:
- 7 + 31526371 = 31526378
- 19 + 31526359 = 31526378
- 61 + 31526317 = 31526378
- 97 + 31526281 = 31526378
- 139 + 31526239 = 31526378
- 151 + 31526227 = 31526378
- 157 + 31526221 = 31526378
- 181 + 31526197 = 31526378
Showing the first eight; more decompositions exist.
