Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527168, here are decompositions:
- 11 + 31527157 = 31527168
- 17 + 31527151 = 31527168
- 19 + 31527149 = 31527168
- 37 + 31527131 = 31527168
- 59 + 31527109 = 31527168
- 61 + 31527107 = 31527168
- 151 + 31527017 = 31527168
- 157 + 31527011 = 31527168
Showing the first eight; more decompositions exist.
