Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541892, here are decompositions:
- 23 + 31541869 = 31541892
- 131 + 31541761 = 31541892
- 199 + 31541693 = 31541892
- 233 + 31541659 = 31541892
- 241 + 31541651 = 31541892
- 281 + 31541611 = 31541892
- 311 + 31541581 = 31541892
- 383 + 31541509 = 31541892
Showing the first eight; more decompositions exist.
