Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526520, here are decompositions:
- 17 + 31526503 = 31526520
- 23 + 31526497 = 31526520
- 31 + 31526489 = 31526520
- 43 + 31526477 = 31526520
- 89 + 31526431 = 31526520
- 97 + 31526423 = 31526520
- 101 + 31526419 = 31526520
- 131 + 31526389 = 31526520
Showing the first eight; more decompositions exist.
