Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526642, here are decompositions:
- 79 + 31526563 = 31526642
- 109 + 31526533 = 31526642
- 139 + 31526503 = 31526642
- 211 + 31526431 = 31526642
- 223 + 31526419 = 31526642
- 271 + 31526371 = 31526642
- 283 + 31526359 = 31526642
- 421 + 31526221 = 31526642
Showing the first eight; more decompositions exist.
