Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526418, here are decompositions:
- 29 + 31526389 = 31526418
- 31 + 31526387 = 31526418
- 47 + 31526371 = 31526418
- 59 + 31526359 = 31526418
- 67 + 31526351 = 31526418
- 101 + 31526317 = 31526418
- 137 + 31526281 = 31526418
- 179 + 31526239 = 31526418
Showing the first eight; more decompositions exist.
