Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541958, here are decompositions:
- 59 + 31541899 = 31541958
- 67 + 31541891 = 31541958
- 89 + 31541869 = 31541958
- 101 + 31541857 = 31541958
- 131 + 31541827 = 31541958
- 197 + 31541761 = 31541958
- 251 + 31541707 = 31541958
- 281 + 31541677 = 31541958
Showing the first eight; more decompositions exist.
