Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527156, here are decompositions:
- 5 + 31527151 = 31527156
- 7 + 31527149 = 31527156
- 13 + 31527143 = 31527156
- 47 + 31527109 = 31527156
- 79 + 31527077 = 31527156
- 109 + 31527047 = 31527156
- 139 + 31527017 = 31527156
- 229 + 31526927 = 31527156
Showing the first eight; more decompositions exist.
