Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527120, here are decompositions:
- 11 + 31527109 = 31527120
- 13 + 31527107 = 31527120
- 43 + 31527077 = 31527120
- 73 + 31527047 = 31527120
- 103 + 31527017 = 31527120
- 109 + 31527011 = 31527120
- 167 + 31526953 = 31527120
- 179 + 31526941 = 31527120
Showing the first eight; more decompositions exist.
