Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525642, here are decompositions:
- 41 + 31525601 = 31525642
- 53 + 31525589 = 31525642
- 89 + 31525553 = 31525642
- 263 + 31525379 = 31525642
- 311 + 31525331 = 31525642
- 353 + 31525289 = 31525642
- 359 + 31525283 = 31525642
- 431 + 31525211 = 31525642
Showing the first eight; more decompositions exist.
