Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527198, here are decompositions:
- 5 + 31527193 = 31527198
- 7 + 31527191 = 31527198
- 41 + 31527157 = 31527198
- 47 + 31527151 = 31527198
- 67 + 31527131 = 31527198
- 89 + 31527109 = 31527198
- 151 + 31527047 = 31527198
- 181 + 31527017 = 31527198
Showing the first eight; more decompositions exist.
