Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526738, here are decompositions:
- 7 + 31526731 = 31526738
- 211 + 31526527 = 31526738
- 241 + 31526497 = 31526738
- 307 + 31526431 = 31526738
- 349 + 31526389 = 31526738
- 367 + 31526371 = 31526738
- 379 + 31526359 = 31526738
- 421 + 31526317 = 31526738
Showing the first eight; more decompositions exist.
