Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527042, here are decompositions:
- 31 + 31527011 = 31527042
- 89 + 31526953 = 31527042
- 101 + 31526941 = 31527042
- 103 + 31526939 = 31527042
- 139 + 31526903 = 31527042
- 149 + 31526893 = 31527042
- 163 + 31526879 = 31527042
- 179 + 31526863 = 31527042
Showing the first eight; more decompositions exist.
